Alright I've seen people doing this and it sounds cool so I am going to give it a shot. These ideas are all originals. Tell me what you think!
Percy:
-stays underwater the whole time
-is annoyed when he is alone in the pool
-splashes Annabeth with a tidal wave of water when she refused to get in and then pretends it wasn't him even though he is the only one who can.
Leo:
-also stays in the pool the whole time
-forgot a towel but its okay because he just lights himself on fire.
-convinced Percy to let him breathe underwater and then abuses this power by pretending to drown and forcing Calypso to save him.
-Jump scares Frank
Frank:
-Stands in shallow side of pool as a human
-shapeshifts into a goldfish when surprised
-collects ring from bottom of pool as a fish
-tries to get Hazel in the water
Jason:
-Swims in the deep end
-Yells at Leo
-doesn't get head wet
-tosses football with Percy, Piper and Frank
-is really uncomfortable seeing Piper in bikini
Annabeth:
-Gets in the water a bit with the girls
-Drinks lemonade by the side of the pool
-tans on towel with Piper
Hazel:
-Refuses to wear a normal one piece swimsuit or bikini, instead wears gym clothes that can get wet
-Doesn't know how to swim
-Puts her feet in water most of the time
-Only gets in when Frank does.
-Holds onto Franks arm the whole time
Piper
-wears cute bikini, towel, and accessories
-flirts with Jason relentlessly
-chills with Annabeth and a lemonade.
-doesn't get wet or touch the water
-plays football from side of pool
Calypso:
-made the lemonade
-is an okay swimmer but prefers to stay out of pool
-is fascinated by the fake waterfall and sits by it
-jumps in pool to save Leo, but yells at him when she realizes it was a fake.
Nico:
-comes because everyone begged him too
-stayed in shadows the whole time
-Didn't get anywhere near pool
-disappeared halfway through party.
