The ice creams deserve better! "It's a Pokemon that's literally just an ice-cream cone -" nooo! It's a living icicle that accumulates snow from the icy environments it lives in on its head, such that the physics of the whole deal make it look like an ice cream cone, and in the Pokemon world, it was the original inspiration for ice cream cones! Come on, I wouldn't have come up with that. I actually find them more interesting than if we'd gotten regular icicle Pokemon. :D
...And the best part? Since the "ice cream" is not actually part of its body, you can eat it if you get hungry in the middle of the night!! (I mean, if you're okay with the taste of snow.)
