A quick guide on how to complete episode 4 of Sam and Max: Beyond Time and Space
The Episode begins with Sam, Max, and Flint breaking into Bosco’s Inconvenience. Once inside, a short cutscene will play. Once it’s over, hop over the counter by clicking on it.
Now that you’re behind the counter, click on the Keypad, the Scrawled Message, and the Toy Moai Head. Hop back over the counter, and walk to the left. Use the Moai Head on the X-ray Machine to get the X-ray, then walk back to the right. Use the X-ray on the X-ray Viewer to receive the code: 5318008.
Now hop back over the counter, and click on the Keypad to have Sam input the code. This will disable the deadly lasers blocking the Restroom. Now enter the Restroom. Once inside, click on the Bathroom Stall, then click on the Wine Bottle. Now take out your Big Gun and shoot the Barrel of Baking Soda. Then use the Vinegar on the Barrel.
You will now be abducted by T-H-E-M, and brought aboard their spaceship to discover Bosco, who’s been turned into a man cow hybrid! After a short conversation (make sure to click on all options) click on the Central Device. Then click on Settings and set it’s personality to Abusive.
Once you’ve done that, click on the Elevator and select the only card there; Bosco’s Time Card. This will take you back in time to the sixties. Once in Ms Bosco’s Convenience Store, talk to Ms Bosco, asking her about “making a baby”. Continue the discussion to learn about the Baby-Maker, who the father was, and how to get DNA samples for the Baby-Maker.
Now try to exit the conversation, only to accidentally make Ms Bosco fall madly in love with Max! It doesn’t matter what you say, nothing will changer her mind. Head to the left, and grab the Modified Carbon Dater. Head further to the left and grab the Chemical Sampler next to the Baby-Maker.
Now take the Modified Carbon Dater and use on Max, Sam, and Ms Bosco. Then click on the Elevator and head back to the Ship. After a short cutscene use all the cards in your inventory with the Elevator. Then click on the Elevator and select Stinky’s Time Card.
Once in Stinky’s head to the right and talk to Little Sam about his machine. Once he tells you he needs a new AI back out of the conversation and take the nearby Screwdriver. Now use the Screwdriver on the Letter Display.
Now head back to the left and use the Chemical Sampler on the Tar Cake. Then head to the Elevator and click on the Intergalactic Freelance Police Time Card. This will take you to the far future of 2108. Now head right to the Bulletin Board and look at the Poster. Then head back to the Elevator and click on the Oval Office Time Card.
Once you’re in the Oval Office head to the far right and talk to Superball. Keep talking to him until you can talk about official duties. Ask for a patent, then patent the Tar Cake with secret ingredient Bitumen-13. Then once you have the patent use the Letter on Superball. Now use the Chemical Sampler on the Envelope Superball threw across the room.
Use the Elevator and head back to Bosco’s. Head to the far left and use the President’s sample on the Open Sample.
Now click on the Elevator and head back to Stinky’s. Once there use the Patent on Grandpa Stinky and then head to the right and use the Portable AI on Little Sam (make sure it’s personality is set to abusive). Then head back to the Elevator, then head back to Ms Bosco’s. Max will have a sleazy conversation with Ms Bosco and repulse her completely, repairing the time stream.
Now use the elevator and click on the Home button to return to the ship.
After the cutscene and the rather nice song and dance number talk to the Old Mariachi and ask him some questions. Once you’ve learned about his deep questions and his dislike of his job, head back into the Bridge, Now that you’re there, take the Embarrasing Idol Time Card. Use the Elevator and click on the Bosco’s time card.
Now that you’re in Bosco’s during the sixties, head to the far left and enter the bathroom. Once inside click on the Wine Bottle next to the toilet to gain a Cork. Now head back to the Elevator and use it, clicking on the Oval Office Timecard. Once in the Oval Office head to the right and use the Modified Carbon Dater on Superball, to gain the Office Timecard. Now head back to the Elevator and use all time cards in your inventory on the Elevator. Then use the Elevator and click on the Office Time Card.
Once in the Office, pick up the Boxing Betty Remote to have a chat with your duture self and get an egg. Then use the Cork on the Model Volcano. Now use the Elevator again clicking on the Intergalactic Freelance Police Time Card.
Once in the Future Office, head to the Bulletin Board and take the Obituary. Use the Elevator again and press the Home button. Exit through the door on the right and use the Obituary on the Old Mariachi. Then run over to the Printer and click on it to open it up (it’s the blocky green thing next to the tube with things shooting up it), then click on the Ink Ribbon to get rid of it. How head back to the Bridge.
On the bridge, click on the Central Device and print a Time Card to get the final Blank Time Card, then use the Blank Time Card on the Elevator. Now click on the Elevator and use the Blank Time Card. This will take you to the very beginning of time itself! Once there, use the Egg on Mr Featherly, and head back to the Spaceship. Head to the right through the door and use Mr. Featherly on the Old Mariachi.
Now head back to The Bridge and talk to the Listening Mariachi to learn that he listens out for birthdays then sings for them. Now head through the Elevator to Sam and Max’s 2000’s office. Once there, talk to Superball and ask if today is his birthday. It is, so don’t forget to say “Happy Birthday!” before you go. Now head back to the Elevator and look at the Time Cards. On the Office Time Card it should say what day is Superball’s birthday. In my playthrough it was the 6th of the 9th, but it may vary depending on your playthrough.
How head back to the Oval Office and head to the right. Click on the giant calendar and change the date to Superball’s Birthday. Then talk to Superball and ask if it’s his birthday. Once he says yes, the Listening Mariachi will appear and begin to sing. While he’s singing, be quick and head back through the Time Elevator back to the Ship.
Once back on the ship, talk to the Captain and chat with him to learn he years for a solo career, but can’t go anywhere without a big break. Use the Elevator and click on the Embarrasing Idol Time Card. Once back in the past, enjoy a quick cutscene and then talk to past Sam and Max. After the conversation, your past selves steal your time machine and leave you stranded. Don’t worry, you catch up.
Once you’re back on the ship, talk to Past Sam. He’ll ask you how to get to the moon. Say he needs a time machine and he’ll ask how to get one. Send him to Agent Superball. Once he gets back, he;ll be confused, but ask how to get to the moon. Tell him he needs a screw driver, and that you’ll trade him one for a Recording Contract. He’ll do the trade, and now give the Recording Contract to the Captain Mariachi.
With the last of the Mariachi dealt with, head through the door on the right and head to the far right around the platform in the middle. Push the bridge button. After the cutscene, quickly run back and click on the Suck Button, then use the Tar Cake Sample on the Time Controls. Quickly run to Bosco’s Corpse and use it to jump up to the Triangle.
Congratulations, you have completed Episode 4.
