Space cave

While traveling to the center of the Earth, a cave was discovered lit by neon plants and small globular Diuphoria (they clean the cave and take care of the plants, the fungi that keep them alive). There is also a large creature of the feline family named Leafest, who guards the place and keeps out predators from other caves that do a lot of damage to the flora and fauna of the place. Leafest feeds on mushrooms and poses no threat to the other inhabitants of this cave. The creature is very friendly and purrs like a cat.
