"Frankie My Dear"
One morning, Mac wakes up to find that he seems to have unintentionally created another imaginary friend named Cheese. Bloo later finds out about Cheese that day, who asks for chocolate milk, just after he finishes bothering Frankie about the drill she needs to fix the bathroom door in the hallway. Bloo tries to give Cheese chocolate milk, but Mac shows up and gives Cheese some apple juice as a substitute, claiming that Cheese is lactose-intolerant.
Madame Foster allows the same rules as there are for Bloo, but Bloo does not approve of his new brother. Mac and Bloo try to finish their go-kart, but Cheese's dim-witted nature nearly stops the construction of the go-kart altogether in multiple ways: First, he uses the drill incorrectly and unscrews the right front wheel. After this, Mac takes the drill from him, and gives Cheese a hammer, which proves to be a mistake, as Cheese causes further damage to the go-kart and hurts his hand with it. When Bloo tries to decided that Cheese shouldn't use the tools, Mac decides that none of them get to use the tools until Bloo and Cheese learn to get along, and are forced to use toy tools, delaying the construction of the go-kart even further. Lastly Bloo and Cheese disagree on whether to paint hot rod flames or bunnies, resulting in Mac yelling at them to be quiet and settles on painting both bunnies and hot rod flames, to Bloo's annoyance.
Cheese also proves to be incredibly weird and annoying, doing things such as putting tinfoil he found in a garbage can on his teeth, and licking various surfaces (floors, walls, etc.) and ruining Mac and Bloo's go-kart ride by screaming loudly every time Mac lets go of the brake. Cheese also proves to be a nuisance to the other imaginary friends, doing things such as screaming "I like cereal" at Eduardo repeatedly and biting Wilt when he tried multiple times to help reach the cereal, angering Coco by first repeatedly saying the one word she knows how to say and then screaming it repeatedly, annoying both her and Mr. Herriman, who puts Cheese in another room, unaware that Frankie is in there busy doing the morning chore of preparing a breakfast of cereal for the imaginary friends in the dining room. Unfortunately for Frankie, Cheese yells "coco" and runs ramming into Frankie spilling the milk and cereal she prepared and destroying the dishes. Frankie then brings Cheese into the TV room where Bloo is enjoying a drink and watching TV and yells at him to watch him. After many attempts to get rid of him, including trying to mail him away, put him up for sale amongst a pile toys at a store, etc, Cheese manages to disappear on his own.
Bloo realizes that a place like Foster's could be extremely dangerous for someone as stupid as Cheese, and just as he's panicking about losing Cheese, he's found by Frankie. Bloo's glad that Cheese is okay and, after giving a speech to Mac, finally accepts Cheese as his brother.
However, a girl name Louise shows up, and is revealed to Cheese's real creator. Mac explains to Bloo that Louise is his next-door neighbor, and adds that Louise explained to him that Cheese gets out sometimes, and they deduce that he must have found a way into Mac's room--this obviously that Bloo and Cheese aren't brothers. Bloo seems disappointed at first, but is later revealed to be relieved that he and Cheese aren't actually brothers.
This episode is considered one of the show's most famous, mainly due to the large amount of humor, its well written story, and the character Cheese. Additionally, the scene where Cheese ruins Mac and Bloo's go-kart ride by screaming whenever Mac lets go of the break, as well as making them pull on the go-kart as it rolls downhill is considered one of the show's most memorable scenes.
