"The End of Casey's Goofiness" is the Season 2 finale of the Disney Channel series Adopteez.
Casey frustrates Chester and his friends with a strong sense of humor and stupidity which limits their plans by dancing to Sonny Eclipse’s songs and the music of the Magic Kingdom parade while watching it, taking Wynter to the Mad Tea Party which was thankfully stopped by Travis and Elaine utilizing their powers, and bringing Lucas to Frozen Ever After.
Then at Disney's Hollywood Studios, Chester and his friends chase Casey and Lucas to the Tower of Terror. The three come back down, but she wants to do it again. But Mitchell retrieves Lucas and reprimands Casey that she has been wasting her time goofing around. Casey, misunderstanding him jokes about the experience which causes to her to laugh hysterically.
Later that night, the gang heads to Fantasmic! During the battle between Sorcerer Mickey and Maleficent, Chester and his friends realize that Casey has disappeared from the audience until they notice her in the steamboat finale, replacing Chip and Dale due to their absence, staying between Donald and Scrooge, waving a long purple strip of paper and throwing it to the audience unlike the characters. As the characters move around, Casey naughtily pulls the Beast's tail which causes him to pound her and attempt to snatch her, but Casey luckily manages to escape from him. Then during the line-up ribbon dance routine, Scrooge tells Casey off for it as the spinning fireworks appear on the moat but she still keeps going.
The next day, Chester threatens her and kicks her out of Walt Disney World and after she lands on her back, she sees the Disney World entrance smiling at it.
- The title is a pun on the VeggieTales video The End of Silliness!?!?.
- Besides Chip and Dale, other characters who have been absent during the Fantasmic! finale include Launchpad McQuack, and Jasmine who is replaced by Kim Possible.
- Wynter saying "Ready to kick it?" is a nod to the Disney XD show, Kickin' It! which stars her actress, Olivia Holt who also plays Kim Crawford as an inspiration to the character.
- Chester's line "For crying out loud, you're probably too stupid to understand me anyway! Huh?" almost references to what Goofy said to Max when he accidentally took the wrong direction in A Goofy Movie.
- When Travis asks Casey as the black sheep of the family "Have you any belongings, Casey?", it is a pun on "have you any wool?" in the nursery rhyme, "Baa, Baa, Black Sheep"; and Chester saying "Casey, that's more than three strikes, and you're out of the ball game!" references the last line of the song "Take Me Out to the Ball Game".
