> Attack store manager
You whip out your knife. So what if this store manager outweighs you by a hundred pounds and has the build of a giant? He's a pushover.
> Stab store manager with Knife
The store manager appears unimpressed. He absorbs the knife into his body.
The manager then morphs into an Absorbent Grue. He smiles, and his teeth are sharper than the knife you previously lost, not to mention he now outweighs you by three hundred pounds.
