S3·E4 Little Watchers / Egg Bound

Little Watchers: Lucien and Tony try to stop water pollution and are accused of making acid rain, so Wayne and Wendy join a club against them. Lucien and Tony try to clear their names out - apparently someone threw a pumpkin.

Egg Bound: Lucien finds an egg in the swamp and takes care of it, and his parents take care of the egg and forget to take care of Wayne.
