Pebble

Pebble is Dandy's pet. Pebble and Cole are NOT related.
But they are most likely friends, because one of Cole's mastery quests requires Pebble to be present in the round.
His name, Pebble, means pebble in English. This may be because he literally is a small pebble. His small size suggests that Dandy named him that.
Pebble's designation is M-001 with the M most likely standing for Main Characters.
He only says "Burk," "Waf," "Woof," and "Wark," but then writes the text in parentheses. For example: "Woof Burk!" (hello!)

Although Pebble can sometimes seem mean and even rude, he's a very kind pebble who doesn't hurt his friends, though he can be very persistent and sometimes growls menacingly. He cares for his owner, Dandy, in a way that many don't. Pebble isn't very talkative for some because he can't speak, only barking and growling. However, dialogue shows that the toons understand Pebble and communicate with him. Like all dogs, he loves being played with and given treats. Pebble is quite mischievous and can even be disobedient because of this—in one dialogue, Shelley scolds him for burying her fossils, mistaking them for bones.

Pebble is a dark gray pebble with a large, flat tail. On his cheek is the outline of a four-leaf clover, light gray in color, the same as his four pointed paws. Pebble has large, expressive eyes that move comically up and down when he plays.
