The original seriesEdit
Rat originally appeared as a purple rat with a pink nose, pink ears, and a pink tail, and wears an orange and yellow cap, an orange vest with yellow teardrops, a yellow bow, big green pants, a green watch, and yellow and white shoes.
The animated seriesEdit
In the animated series, his appearance is arguably changed the most out of all the cast who appeared in the original series. He is now grey instead of purple, has a black nose, and now wears new clothes such as a red cap, a cyan shirt with a collar, and blue pants with a belt. His size has also been altered to the size of a usual rat.
Rat sings his own song in the shop when he prepares to run it.
I'm a rat, I'm a rat, I'm a busy, busy rat.
I'm a rat, I'm a rat, I'm a clever, clever rat.
