Dr. XyliCube

 (Korean: 닥터리톨, daktoritol, "Dr. Erythritol") is an Epic Pet released alongside in the second half of The Sweet Signals From Space update. It absorbs Jellies ahead at regular intervals, where it then spits out Purified Bear Jellies and multiple Xylitol Particle Jellies.

Story
''Meet the first Cube Robot managing the Xylitol Planet Central System. According to the data input by Xylitol Nova Cookie, this robot cleverly identifies potential threats to the planet like a pair of precision pincers. It may seem docile, with eyes closed in a seemingly calm manner, but Dr. XyliCube is keeping a watchful eye on everything! If you happen to catch its attention on the Pet's radar, brace yourself, and good luck!''

Trivia

 * 's internal name is "pet0237".
 * Dr. XyliCube was originally meant to produce red Purified Bear Jellies in their skill, as seen on their sprite sheet. These would presumably recover energy, in which leveling up the pet causes more energy to be restored, much like with $π$ after the Spooky School Experience update. Before the final release, these red Purified Bear Jellies were removed from the skill.
