Galax

The Galax is a small alien plant hailing from the planet Parvus. Like all life on Parvus, it lives underground in caves, however the dangerous conditions on the world have reduced the species to a single specimen. When threatened, the Galax can spray a sticky purple substance that coats its attacker.

"The Big, Small Rescue"
Boulder took the Rescue Bot recruits to Parvus via the space bridge and assigned them the task of rescuing the Galax as the cave it was in had become unstable as the result of some recent quakes. Their initial attempts resulted in Wedge being coated in goo, but they eventually managed to extract the Galax, still stuck on a rock. During their subsequent escape, the Galax actually managed to save itself and Whirl from a rock fall using its spray attack. Back on Earth, the Galax was installed in a terranium where it reproduced and a new Galax started to grow alongside it.
