I like the velcro idea.
Maybe if you pick up like 10 dretchs you can become a big rolling ball of death, any humans you touch die, also, the dretchs absorb the fire and fall off.
Oh yeah, and howze about the fartfire cannon XL80V2 for the humans, it requires 2 humans to operate, well, one is the cannon, the other loads, fires and lights the, um, gaseous projectile.
Savage.
