Art of Vicious Polymorph

Target creature becomes a 0/1 Jelly with Shroud that can't attack or block.
Smoothly rounded, with no mouth, with pulsing white holes filled by fog where eyes used to be. Rubbery appendages that were once arms; bulks rounding down into legless humps of soft slippery matter. I have no mouth. And I must scream. - Harlan Ellison, "I Have No Mouth,
and I Must Scream"
