What does the rainbow poop do?

I ran into this rainbow poop.

Rainbow Poop

Breaking it caused a nice sound effect and a rainbow to pop up on the screen. Did it do something else too, or is that all it does? Was I unlucky and got something I already had, like full health?


Solution 1:

This is all we know so far:

  • Causes a rainbow to appear on the screen
  • Can also drop coins, keys bombs or hearts.
  • Gives full health upon destruction.
