Soft rocks

I'd get really small ones then put them at the bottom of a ledge or something then freak everyone out when I trip and fall onto them.

Those look so comfortable

What rocks were actually soft but they just tense up when we touch them?!?!?

Plot twist : its a real rock

Id mix real ones with those.

Imagine if you bought a whole bunch and then satan just placed a real rock right in the middle.
