I followed you into the chamber, stole the cookie, and gave it to Merlin ze Wizard.

I boiled Merlin alive in oil

Well Merlin magically teleported before you could boil him.

While you two are fighting with Merlin, I grab the cookie and give it to King Arthur and hire his knights to protect it.

I shape shift into one of the guards, steal the cookie,a and give it to the moon pearl princess :D

I turn into a moon dragon and trick the moon princess. I grab the cookie and give it to Morgan le Fay so she can protect it with her magic.

I use my Magicks to explode Morgan Le Fay and steal the cookie, I hide it in a peanut butter factory

I use a cookie detector spell, grab the cookie and hide it in a bakery that is as big as the U.S.

I use the detector GPS and find the cookie. When I find it I put it into the Transformice game :D

Just steals cookie and takes it to space
