|— The Locals Forever|
Tater Tot has a stumpy green body with a thin neck, a short tail, two round buttons on her chest, and large eyes. She almost always wears a green helmet with a large fin on the top and a fish image on the front.
In her powered up form as seen in Together Forever, her helmet changes slightly and she gains a third chest button and a much longer and more powerful tail.
Cheerful, friendly, and would do anything for Twelve. She has a "sassy" side as noted by Esther when the trio eavesdropped on her and her neglectful roommate Garrett having an argument in the episode The Locals Forever.
