A pitiful blob-like creature of unknown species is one of the many captives of Mary and Fred, and the only one who has not managed to escape. It was voiced by Wally Wingert (who is also the voice of Almighty Tallest Red). Its only appearance was in the episode "Abducted".
The blob is a doughy and pale creature, lacking legs and vaguely resembling a slug. It possess stumpy arms, though they are rendered useless because of the many objects "fused" to its head, including a fork and a moose-like animal, which weigh it down and render it unable to move around much. Additionally, the blob creature has two tiny (possibly vestigial) nubs on its head and large green eyes.
The blob creature is very miserable, having been left in its subject tube to rot, and has no problem expressing it. When it attempted to get Zim to help it escape and failed to attract his interest, it began to weep. However, when it first met Zim, it was able to smile slightly, though it went back to its dejected state in a matter of seconds. It is also quite naïve, as it actually believed that it was fused with the assortment of random objects taped to its head.
Role In Invader Zim
Zim met the captured blob in "Abducted" as he tried to escape from Mary and Fred's ship. The blob cried to him for help, but was ignored, emphasizing Zim's apathy.
