Could one feel these crawling around inside??


I can, just looking at it.



Four or five as a bunch might be a cause for concern… just looking at 'em!



I just happy that these will only ever be used for good.





I want to send these down my kitchen sink drain to find where it keeps getting plugged up! I’m sure I’ve got some mini fatbergs going on down there.


I’m guessing use of these is gonna be with anesthetic so you can’t feel it, or at least a sedative so you don’t particularly care that something’s moving inside you.


could be made to move fat burgers



Oooh! Oooh! It tickles!!!
