The Spotted Glistening Meadow Worms are a rare species of worm that only appear in the episode "Pet or Pests."
Adult Spotted Glistening Meadow Worms are about three inches long. Newborns are extremely short. They are light pink in color and have a darker shade of pink on their legs.
They tend to move like an inchworm. snails are their enemies, like said snails and worms.
Newborns spit out a green secretion for an unknown reason. This is most likely for self-defense.
It is unknown how a Meadow Worm reproduces exactly. From the episode, Mrs. Wormsley was pregnant for approximately one 24-hour period. The worm would stay under something probably in order to ensure its young's safety. Its belly was stretched out only until its children's birth,,which was the next day.
The adults make a nest out of what seems to be brown, dead seaweed. Under that seaweed is a small hole which its size varies from the adult's. When a large object impacts on the nest, it easily breaks apart.
Since this worm is a rare species, it can be noted that this animal is threatened or endangered. However, when Mr. Krabs sold these worms, there is a possibility that they can still be sold on the market. Otherwise, he was violating and avoiding the law, which is no surprise, considering his long-term criminal history throughout the series.
Mrs. Wormsley is the most notable specimen of its species. She has five young childrem, who all look similar.
