Had a couple side scene related ideas. First, it would be fun to have a Skitty/Delcatty as a reference to the Hot Skitty on Wailord Action meme. Even have a good opportunity to introduce it since May has a Skitty in the anime and she was also out for the Wailord. The excuse could be that May's researching how a Pokemon that small can fit that much cock, and maybe part of the scene could be escalating the MC's size inside of her. Probably steps on Mew's toes a bit though.
Second thing is a couple of small thoughts for the Contest Minigame you mentioned at the Fishing Preview. Could use the MC's knowledge of Pokemon breeding and say he's there to help with pedigree breeding or the like. I also think it would be cool to use Purugly with this premise, but there's not much rationale there besides that a Purugly would stacked.
