Steps to reproduce
Get a red koopa shell, specifically a red one to make it more noticable, do not throw it since that'll just bump it out. Let it wake up in the block.
Other occurences
This trick actually seems to work on any tile. However the part where it wakes up does not. You can get a red koopa shell in a different tile and actually kick it through.
Expected Results
It shouldn't get trapped at all. Simple
