These two blocks, will either freeze Mario immediately, then disappear in a puff of smoke, or freeze Mario over time, but not disappear in a puff of smoke depending which on you use. They also both disapear in a puff of smoke when hit by a fireball. No credit needed. Lastly, the readme explains which one is which.
That's weird, the block that doesn't disappear doesn't work for me. It keeps freezing me every like half second and I can't move anymore (because I'm constantly frozen).
I tried huge and small values for both !time and !cooldown
