Invincible Sidekicks, THEN and NOW!

Gee, I see what you did there NINTENDO! (Perhaps I am the only one who thought of such thing lol)

But hey! what's this? An hero with a OP sidekick? I've seen this before...

Anyway I remember the ol' days of Sonic 2 n' 3 where the 2nd player could control Tails and make your guinea pig (fox) and try stuff without bein' penalized like losing rings or a life but at the same time it couldn't get the power ups, it all went to Sonic, but that made him a good way for newer players to get in!
And I feel that Nabbit it's basically that idea but in a Mario game, only that his invincibility it's quite mentioned (you see, ol' Tails it's quite a modest fox) and that's why the reason of the similarities... well to me at least! Enjoy!
