You should not be able to cancel shambler's devour by just grabbing it

[GARGATHUGANOKSREVENG]

The writhing mass of flesh that can turn any part of its body into gnashing teeth to eat you suddenly decides it will just allow you to grab a part of it, yank it around, and suplex it (requiring you to basically hug it)? Seems silly to me.

yeah ok but it's funny to suplex giant aliens and we shouldn't let realism get in our way there

besides that the idea on making limbs/bodies give DNA is solid
