Lets start posting ideas for killing these alien things lol!
So far we have:
Tag and a lighter : Flame to death.
Bugspray.
Squish em.
Hit it with a hammer!
Weedwhacker
M80
Cherry bomb
Paintball gun
Run over it with an rc car
Dagger tied to a stick
Electric shock
Drown it
A weird one - Throw pastries (donuts, cakes, brownies) at it, like a custard donut.
Throw glass bottles
Cover it in plaster
Smash it with an old guitar that you were gonna get rid of
Pour syrup on it or bbq sauce (it cant move and possibly die in it)
Carry a shuriken?
Pour hydrocloric acid on it.
Get a mouthfull of kerosine oil and a zippo or lighter and blow the son of a b*^ch to h*ll lol
Super glue works as well. It gets stuck and then it hardens
Stick it in a microwave (watch it explode)
(Lets keep going. Think of creative ways to kill these things)
