Yeah, Ice Climbers could do it too. But, you know, at LEAST they had some glaring and very crippling weaknesses to kind of not really balance it out. Like, the fact that Nana didn't respawn, and how Popo by himself was one of the weakest characters in both games. Luma respawns every 8/13 seconds, and Rosie is quite far from being a weak character even on her own. Not saying at all that it was OK at all for the ICs to have it, no. Puppet characters are always going to be a problem when it comes to balance. But yeah, Rosie's still good, she doesn't need it. If Rosie players have such a problem with it, they could just, y'know, not let themselves get grabbed.
