I hold the many teeth in your pocket that you need to get through all the locked obstacles in your path.

A place rest and unwind while clean bubbles help me remove the daily grime

I lie in water yet never swim, I rise between rivals yet never play, I hum unseen yet carry the whole wide world.

I fill others yet I am empty at my center. I can start as everything but always end as nothing. I have the power to allow you to eat pizza at any hour of the day.

I am hard and cold. I have something missing in me leaving a hole in my heart. The key to my salvation lies with how well you can Tumble me.
