I replied, "I'm trying to disarm a trap. You should probably wait here until I'm done, just to be safe."
As the rest of the group nibbled their snack and watched me do all the work, I dragged what was left of the rats around the corner into the partially sunlit chamber. I made a neat pile of them in a corner near the pile of gold coins.
Then I carefully counted the gold coins on the floor. I counted 14 coins. From my Bag of Tricks I removed 14 of my own coins and hefted them in my hands to guage their weight. I even made myself just weightless enough to float with them in my hands.
Then, using my toes, I grabbed the tails of the various snake and rat parts, which made me look a little like a baloon on a string. Without changing my weightlessishness, I dropped my coins on the floor one by one. I was still a baloon tugging on a pile of rats. Using my fingers, I pried rat tails away from my toes one at a time until I just started to float again.
Now that I knew exactly how many rats to use, I drifted the precisely calibrated pile of rats over to the sunlit pile of coins and gently touched down onto the treasure. One by one I picked up the coins while letting the rats settle onto the same floor stones. When I was done, the rats were neatly piled on the floor and my weightless coins and I drifted safely away.
