I Filled My Brother’s House With Slime & Bought Him A New One

 is a creative video created by MrBeast. In this video, Jimmy, Chandler, Chris, Karl, and special scientist guest Mark Rober filled the house of Jimmy's brother, CJ Donaldson, with elephant toothpaste.

Mark Rober is known for holding two world records using elephant toothpaste, which is 290 gallons, but in this video, they used 14 barrels of elephant toothpaste, or around 500 gallons, in CJ's house. The crew received permission from CJ's roommate to use the house, so after CJ saw his house, MrBeast gave him a new one.

The pranked victim on the MrBeast channel was CJ, while on CJ's channel MrBro, Karl was the pranked victim, because CJ's crew covered his house with sticky notes, hence why Jimmy said "Brady's house" in front of Karl, to not spoil his brother's video and to not reveal that he was pranked.

Mini-Challenge
This video was sponsored by Apex Legends, hence why Chris, Chandler, and Karl played a battle royale game of Apex Legends. If they win, Karl's mother receives $10,000, and if not, they get slimed on themselves.

All three of them lost, but only Chris and Karl got slimed but Chandler got an exception because while not winning, Chandler got plenty of kills in the game.

Trivia

 * CJ's crew misspelled Karl's name, where they spelled it as "Carl". This was also shown in the video, I Bought The World's Largest Firework ($600,000).
