Peppa's gang's treehouse is where Peppa and her gang have meetings. Inside, it has a poster of three puddle-jumping kids, a poster of Superpig and a poster of Mr. Potato and his family. It is located in the backyard at Peppa Pig's House and was built on the same day Peppa formed a gang to rival Emily's clique. The treehouse has a sign saying 'TREEHOUSE' above the entrance.
In the game, the treehouse is replaced as the gang’s base by Peppa’s basement. The treehouse, however, can still be visited in Peppa’s backyard. It contains a chest with the Treehouse Badge.
