During the summer, the seven play hide and seek in the woods at camp half-blood.

Annabeth hides in the trees, Percy hides in the ponds. Hazel and Nico hide in caves, Leo stands around posing waiting for the seeker to find him looking fabulous, and Jason and Piper fly above the trees, but Frank wins every time cause he just changes into a squirrel or a bunny and no one even tries to figure out if it's Frank after the last time when they had a "misunderstanding" with a rabid beaver.
