Slimy, A.K.A. Experiment 390, is an illegal genetic experiment created by Jumba Jookiba. He is designed to leave slippery slug trails. He was captured by Gantu, but was rescued in "Snafu". His one true place is making a sci-fi green waterslide at parties. He is voiced by Frank Welker.
Slimy is a large green slug-like experiment with black eyes on his stalk, a thin mouth, three spines on his back, and a semi-gelatinous body without legs or arms.
Slimy produces a thick, slippery green slime similar to that of a snail.
- Strangely, Slimy seems to change from dark green and light green to dull blue and dirty clear. It is unknown how or why this happens, but he is shown twice in Leroy & Stitch like this, and his green version did not appear (although this could have been Clipse).
- Slimy also changes in size from large in Stitch! The Movie to small in "627", most likely due to releasing slime.
- Slimy's pod color is red.
- Slimy is described by the experiment computer screen as, "Experiment 390. Primary function: Slime producer".
