All Consuming Fire...Ant

This golden ant figurine is imbued with a ferocious purpose. To consume. 

If the figurine is laid on a dead creature, and a command word is spoken repeatedly for 12 seconds, millions of ants gush out of the figurine in blinding speed to consume the creature...bones and all. 6 seconds for a tiny creature, and an additional 6 seconds per size increase. 6s=T, 12s=S, 18s=M, 24s=L, 30s=H, and 36s=G. 

If placed on an active undead creature, the ants become confused and react wildly & randomly. 

If placed on a living being, the ants simply refuse to spawn. No one knows why.
