"Slime-san was minding his own business, sliming around in a peaceful forest when suddenly…A giant worm appeared and gobbled him up! Now deep within the worm’s belly, Slime-san has to face a decision: Be digested by the incoming wall of stomach acid... Or jump, slide and slime his way through the worms intestines and back out its mouth! " The standalone expansion content was added to the base game through free updates. The Xbox and PlayStation 4 release is under the version title Slime-san: Superslime Edition. The Nintendo Switch release will be updated to the new version as well.
