The tentacle dissipates into a bunch of perfectly ordinary MOUSE CLONES and CUPCAKES. Dead ones, anyway. Hakeem shields Gadget's eyes from the upsetting sight of so many of her identical fallen siblings.

If this is what the tentacles are made of, you hypothesize that the entire AMORPHOUS LOVECRAFTIAN MASS is mostly the result of a whole bunch of MOUSE ABOMINATIONS and CUPCAKE ABOMINATIONS multiplying and combining themselves at an exponential rate until their form broke down completely. Jeez, those things have been *busy* since you last saw them.
