Emotion Commotion! is the sixteenth episode of Season 4.
After coming out of a pool naked in front of all his classmates, Timmy wishes he had no emotions.

His fairies grant his wish, sucking out every emotion into live personifications that they lock in a box. He was radiant that Trixie wants him to be her new boyfriend.
Soon afterwards, Timmy is approached by a daredevil to perform a jump through a ring of fire, with a pair of large scissors. Then some villain kidnapped Trixie and Chester and Timmy has to save them. Then he realized that he can't let fear control his actions. He jumped off and died; Cosmo realized that he forgot to give Timmy back his common sense, which would've been useful in wishing both Trixie and Chester free.. Timmy has no fear, terror, embarrassment, rage, hatred, alarm, shock, sorrow and ecstacy and depression learns that having emotions is better than not having any at all! He then punishes Cosmo by unleashing a piranha on him.
