A little monkey lives in the forest and loves to eat candy and junk food all the time despite his mother's warnings. One day, the monkey's tooth starts hurting badly. His mother takes him to see the dentist mouse. Along the way, they get directions from Mr. Kangaroo and Mr. Giraffe to find the dentist mouse near the lake. The dentist mouse treats the monkey's toothache, telling him not to be greedy and eat too many sweets. The monkey promises to listen.
