Which two cute Pokémon would you merge? How would it look like? What do you think of it?
I don't really know about merging cute Pokemon, or merging Pokemon in general. A lot of the possible outcomes I can think of are utterly terrifying, and for those who aren't, they just don't retain their cuteness. But I guess that's because I keep thinking of giving Pokemon additional limbs from other Pokemon, and an Eevee with a Pikachu head as well just isn't thaaat appealing of a Pokemon.
But then again, the things that make the Pokemon cute are their individual factors of cuteness. The creatures we do find cute, are the ones who have something in common with human babies, which ranges from a lot of things, like their size, what noises they make, etc. What appears to be the most common though, is anything with a small body, large head and large eyes, which may be the reason so many people love Eevee so much. That's pretty much why fusing two cute creatures may make the result less cute, since it may add and remove several cute factors that in the end may not make a good recipe for cuteness. Or at least so I assume.
Regardless, I'm sure there are possibilities of fusing two Pokemon and still have them remain cute, but I just don't have the creativity for that :(
