I think being able to use a Prisma Philter after hatching an egg would be a pretty useful concept. I know I'm not the only person that has accidentally gotten into an egg-hatch fog and completely forgotten to use a Prisma Philter to hatch their eggs. My suggestion would be to ask if we can make it to where any hatchling could still have the ability to have a Prisma Philter put on it, even after it's hatched?
