I has three:

Crocalor: This one is less bad than the others, but lets dive in. I like some parts of its design, like the nest/ sombrero. But it falls into the trap that a lot of starter middle evos fall into of trying to be cute and cool like the other members of its family, but end up looking doofy. This is another unfortunate entry in the weird round starter middle evolutions.

Shroodle: What even is this? I know that some pokemon are fantastical, but this? The only thing this looks like is a rodent skull, and even that is a stretch. Unique type combination does not excuse this abomination.

Flittle: If I was confused with shroodle, now this, this is just sad. Its ugly yellow, has a stupid surprised face, and weird pigtails in its anatomy. Absolutely disgusting.
