Eh, I dont like Kiddy or Ellie. The rest sounds good, though.
Eh, lots of fans were put off by Rambi being taken out for Ellie. If she was alongside Rambi maybe that would be okay for some. Kiddy was hated by many for his sluggish movements. I know lots of fans that do not approve of them. It is cool. ^_^
Are those your reasons too?
I noticed Kiddy moved faster in the GBA version, or seemed too. Maybe the controls were more responsive. No clue, but I did not like him as much either when I first played the SNES game, but then he grew on me.
Ellie and Rambi have different abilities, so I have no idea how that could be redundant. Similar to the purple and green versions of Squawks being in the same game. Ellie shoots water and is more ranged, Rambi is more of a tank.
Kiddy is stronger than DK, and had different abilities so your point made no sense. DK was also kidnapped at that time. It made sense to give Dixie a partner and make another duo similar to Diddy and DK.
These are not attacks against you, but those reasons kind of suck.
Ok, fine. Ellie isn't all that bad (I forgot about the water thing). I still hate Kiddy, though because again, he's a whining baby. And the noise he makes when he dies hurts my ears. And he's ugly. I'm glad they quit using him.
Chunky was ok, though. I legit miss him.
oh reality, it's not for me and it makes me laugh oh, fantasy world and disney girls i'm coming back

So how did Baby Mario work out for you in Yoshi's Island? He was even more useless and loud. I do admit that crying is crazy. Kiddy crying hurt. He is super cute, though. Those blue footsy pajamas. Aw!
