My KDL3 favourite Animal friend is Nago. He's ok, although Pitch has better abilitys.
BTW, the thing it annoys me the most of KDL3 is the the ability Clean can only be found in that game, and the thing i hate about the Dark Matter games (KDL2,KDL3 and K64) is that the abilities are random-looking and the Clean ability didn't appear in any other Kirby game, so i dont know how its moves will be if it appeared in games like KSSU or Return to Dreamland
My second favourite is Coo, then probably Kine. I think Coo looks super cool, and Kine I find him really cute.
I don't mind that they're random. I think it makes them more special and unique. Also for those games you needed certain abilities to clear certain things more than the newer games, so I guess that's why they don't appear more.
My favourite Animal friend is Coo. he's a badass and a lone wolf (because he doesn't have any relatives) and i like lone wolf characters. Whats your favourite Nago Ability? for Coo, i like his Spark ability
