A crumble block (weak block in Kongregate Racing) is a block type in Kongregate Racing and the Platform Racing series introduced in Platform Racing 2.
Properties[]
Crumble blocks will shatter away into pieces after players hit them too hard or too much.
If players fall into a line of crumble blocks at top speed in PR2, they will all break instantly and players won't stop until they either reach the bottom or another block type. This was changed in PR3 to always require crumble blocks to take at least 2 hits from players to break, though the new Rocket Launcher item can still shatter lines of them instantly.
Players wearing the Top Hat in PR3 are able to pass through the sides and bottom of the block.
They're also the only blocks in PR2 unaffected by the Santa Hat after its 2013 update.
