The Pebbles and Bamm-Bamm Show - Season 1 - Eps 16: The Birthday Present
Wooly takes the gift that Pebbles bought for her mother and buries it in the back yard. Pebbles believes it was stolen by her neighbor the creepy Mrs. Gruesome, so she offers to babysit for the Gruesomes so that the kids can infiltrate the Gruesome mansion and search for the gift. Thinking that Mrs. Gruesome may have the gift with her, the gang then crashes a Gruesome family reunion, and Bamm-Bamm is mistaken for a cat burglar.
