Mr. Blizzard is a snowman who first appeared in Super Mario 64, but was nothing like this. When newer games came such as Super Mario 64 DS and Mario Party 7 he got this look. Anyways his face looks similar to a Freezy's face. I made this using a snwo texture I have, eyes from a Mushroom, stick arm used from a Pipe and the mitten from Big Bob-omb's MP9 art.
This is the Blooper Mushroom. If you eat this, you'll turn into a blooper. You'll get a blooper suit and it allows to shoot ink to enemies. Plus you can swim longer like the Frog Suit and the Penguin Suit. This power-up is only available at underwater levels.
I made this power-up which is based from the creators Misskatt66 and OnionRingz64. Sorry this doesn't look like it but I hope it suits you well this power-up.
