You go in through one hole, you come out through three holes.
Once you’re inside you’re ready to go outside, but once you’re outside you’re still inside.
What is it?
I am the type of room you can not enter or leave. Raise from the ground below. I could be poisonous or a delicious treat. What am I?
I can come in three forms
But this is my solid state
And when I'm hard enough
On me you're able to skate
What am I?
