Dil We Meet Again Rugrats : Season 6 Episode 16

The grown-ups prepare for a block party. After Betty warned the Rugrats that Dil will become a watermelon if he eats too much of it, they thought that it happened when Didi took Dil inside to clean him up and was replaced at that spot with a watermelon, while they saw Chazz making balloon animals. The worst part is that watermelon is going to be part of a watermelon-eating contest.
