Personality
Timmy is a small, yet smart, twina. He is secretly a secret agent, and, when in secret-agent mode, used to defeat Quag in his evil attempts to take over the moon. He is now currently under the imprisonment of Leader Plankton at the Bucket of Evil. He is sort of like Perry the Platypus from Phineas And Ferb because Timmy and him are both secretly agents when they aren't in pet mode.

Trivia

 * He is the pet of Missita and Lahoonamine.
 * He now resides with SpongeBob in a cell located in Leader Plankton!.
 * He hasn't died underwater because twinas have the ability to breathe underwater.
 * In Season 1, he had the role of a main character in the Stuck On The Moon Segment but since there is no Stuck On The Moon Segment in Season 2, he has been downgraded to a recurring character. Ironically, despite his status being downgraded he appears in more S2 episodes than S1 episodes. This is likely due to S2 having more episodes than S1.
