Idea 1: a hammer that tux can throw or attack with, like the super hammer from mario maker kinda... but only one at a time, either thrown or being held...
idea 2: the revenge in redmond cape... It lets you spin attack or in the air, it could be timed to act like mario world's spin jump... for a second... trying to use it on something that isn't vulnerable from the side will bounce you off harmlessly...
idea 3: a santa hat that just counts as an extra hit; getting hit will just revert you to bigtux, that's all... (get an egg while you're bigtux)
idea 4: A hyper fish that makes tux jump higher and run a bit faster; running into an enemy like this, if they visually don't have spikes, will actually bounce you back harmlessly instead of making you lost a powerup... however, it's only temporary, like the star...
Feel free to post more ideas yourself!

I'd like to see improvements to the ice flower, where maybe instead of shooting bullets like the fire flower, you can punch and kill things using "ice fists."

...that's boxer/boxeur tux from the old wiki... Also, too close range and risky... maybe have it go flying like a kicked ice cube, but instead of bouncing off of a wall, it dies...

So, like freezing an enemy in NSMBW?

kinda... but it acts like it was thrown the instant it gets frozen...
Also, for enemies that explode on death, like mr bombs and haywires...
... there should be a few particles of ice shards flying from the explosion...

Maybe Something Like The Climber Helmet?
Something That Allows Tux To Climb Up Walls.

... may be too hard to code that, and it may be as much of a game breaker, if not even worse, than the air flower...
Unless, you meant it like the cat bell from SM3D World... that... wouldn't really be a bad idea...

I like the hammer idea, it kinda goes in the vein with a different thread here with the grappling hook.

Nice!

Yup. I Meant The Cat Bell.
