Camp Over Here-Over There

Camp Over Here/Over There is the one hundred and sixty eighth episode from Season 1.

Plot
Dennis and friends are camping at Camp Over Here. Sidney, the camp owner is showing off activities that can be done there, while Dennis starts off a prank by painting over a picture of a boy. Dennis is on PeeBee's shoulders, who is on Tommy's shoulders. The camp owner tries to stop Dennis from doing what he's doing, only to get caught in a trap Dennis and friends planted. But Dennis, PeeBee, and Tommy lose their balance and fall over, resulting in PeeBee getting covered in white paint.

Over at the girl camp, Margaret, Gina, and Maria are throwing mud at a picture of a girl. While Gwendoline, the owner of the girl camp explains they're not allowed at the boy camp. Upon seeing what Margaret, Gina and Maria are doing, she ordered them to stop, only to land in a trap they dug for her. Margaret, Gina and Maria offer to help her. Meanwhile, Dennis and Tommy use an inflatable boat to sneak over to the girl camp while carrying a sack, ready to cause the girls to freak out. PeeBee didn't join them because he was in the shower.

Unbeknownst to the boys, Margaret, Gina and Maria used a canoe to sneak over to the boy camp with something in a sack. They've arrived at the same place Dennis and Tommy arrived at. When Gwendoline goes into her cabin, she runs out in fright. As it turns out, Dennis and Tommy were dressed as frogs. Turns out the Dennis and Tommy made a mistake. The girls were playing a prank over the other cabin. Gina puts a toy snake on PeeBee, and then the girls run off. Sidney runs to see what's going on, only to find that someone put a bucket of water on one of the doors that falls on his head. Sidney blames Dennis for this.

The next prank involves a remote control hot air balloon PeeBee invented. Dennis explains that there's something inside that'll make the girls scream. None of them knew that Margaret, Gina, and Maria had a trick up their sleeves. Maria pulled a wooden fan, and made the balloon blow back toward the boys. Once the balloon returned to the boys, Margaret used a slingshot to open the balloon, and as it turns out, the balloon was full of bugs.

Gwendoline takes the slingshot off Margaret, and decides to use it for herself. She aims for the camp shower, and the shower falls apart, revealing that Sidney was in it. This causes the boys to laugh, and Sidney to blame Dennis for the prank. The two camp owners tell their respective campers not to go across the lake under any circumstance. Since none of the owners mentioned anything about digging, Dennis, Tommy, PeeBee, Margaret, Gina, and Maria start digging under the lake.

Unintentionally, Dennis, PeeBee and Tommy dig under the owner's waterpipe. This is the last straw for Sidney, since he plans to call their parents. That evening, Henry takes Dennis, Tommy and PeeBee home. Dennis is unfortunate that he didn't get to see their best trick happen on the girls. PeeBee wonders what last trick the girls were going to pull on them. The two camp owners are on their canoes, pleased that PeeBee, Tommy, Dennis, Maria, Gina and Margaret are gone. When the two camp owners start singing, their boats spring a leak and they sink. Turns out the boys and girls' last trick was putting a hole in their canoes.
