Tinker Bell: The mouse's name is Cheese?
Bobble: Must be. He always comes when we yell it!
Cheese is a mouse with a sweet disposition who typically pulls carts for the tinker fairies. He is good friends with many of them, especially Tinker Bell, Clank and Bobble.
In Tinker Bell, he helps Tink and the other tinker several times. Also he helped Tink try and catch the sprinting thistles, which ends up back firing on Tink.
Later in Tinker Bell and the Lost Treasure, he helps other fairies prepare for the Autumn Revelry. At the beginning he helped Tinker Bell test the "Pixie Dust Express."
In Tinker Bell and the Great Fairy Rescue, he came along with the fairies to Fairy camp. He made a appearance at the end with Mr. Twitches, who made him nervous when he started petting him.
