John: Screams 'shark!' To scare you then pushes you back into the water when you try to escape. But ends up laughing so hard even after realizing he 'almost killed you', so he apologizes while laughing and helping you out of the water.
Paul: Listens to music with you as he sits in the sand with you, talking about everything.
George: Holds hands with you and walks down the beach on the shore with you.
Ringo: Buys you candy and food then plays marco polo with you in the water.
