So now we have mobile spiked walls. French tribes will love this dino

It impales its foes alive slowly drowning its victims in its own blood.
I'll name him Mr. Puffles!

GUYS I GOT A GAME!
Kentro darts!
Throw dodos at a set spike from a good distance and the first person to get 2 stuck in the spike wins!

There like a Lego with legs....you don't wannna step on em!
