I've had some silly ideas, but I've been too shy to bring them up, and with my summer internship+new job, I probably won't have time to do them myself. So... i'm offering them up if anyone wants to take 'em and plan 'em and whatnot.

Anyway.

Music Plot - A swarm of Whismur/Loudred/Exploud take over the Goldenrod Radio Tower! Along with some techno-babble and other musically-talented Pokemon, this strange phenomenon causes whoever has their radio on to burst into song. It can be from their own canon, something their voice actor did, or just making them do Sexyback for the hell of it.

Hades and Persephone Plot - It's sunny, so why is it snowing? There's a mix of hailstones as a harsh wind blows! Why is it so hot when the rain is freezing cold? A Pokemon Professor finally deciphers the answer - there's a powerful Castform wandering over Johto, looking for it's kidnapped friend, a missing Lilligant! Trainers will have to search high and low for Lilligant... and they'll find that the kidnapper was a Houndoom, who just wanted to play with her :( reunite the friends to restore the weather to normal!

I Am Who? Plot - Some of Team Rocket's sillier scientists think they have stumbled upon their greatest scheme! With a combination of Jigglypuff's hypnotic singing and Spinda's swirls, everyone who tunes into their Pokemon gears will go into a trance! But the results aren't quite what they expected... instead of submitting to TR's will, everyone's personality has been switched to the last person they talked to! For example, Minnie Mouse has become a stern and formidable woman of battle, while Lightning is now a girly romantic princess! It'll take some time to wear off, but some shenanigans are bound to ensue.

I'm probably forgetting some, but if you want 'em, have at 'em, edit 'em, do what you want, I was bored and wanted to type.
