headcanon that percy wakes up every day, just absolutely pissed about one thing in particular
like sometimes, it's entirely valid. he's mad about ocean pollution or something like that, and he spends a day in the long island sound and tries his best to clean it up.
the next day, he's mad that blue raspberries don't exist.
just like the tide, his anger changes, and he spends the entire day bugging the demeter kids to grow blue raspberries.
they go to annabeth to ask her to stop him, and she tries. she tries by dyeing normal raspberries blue, but he takes a look and notices immediately that they're not blue raspberries. somehow, he knows what blue raspberries look like, even though they don't exist.
eventually, he gets the demeter kids to give in, and they manage to plant the first blue raspberries ever. percy is so excited that he begins drawing up plans to mass produce them, but alas, it's getting late, and he's getting tired.
when he wakes up the next morning, he's grumbling about the poaching of whales when he sees the plans on his desk, and he has no idea how they got there. he thinks he's getting pranked, so he throws them in the trash.
when he walks outside and passes by the demeter cabin, however, he notices something strange going on. they're celebrating... surviving his "stupid" demands for the 50th time?
percy at least every three seconds:
