Moon Mortar's life is devoted in creating the PERFECT Full Moon Rice Cake Jelly. Even though its Full Moon Rice Cake Jellies are tasty and beautiful already, it's never enough for this Pet. All the "failed" rice cakes are happily consumed by Moon Rabbit Cookie.
The Honey Mortar currently generates the most points per jelly in the game at 600,000 points each. The second highest valued jellies in the game are Giant Bear Jelly and Flying Coin at just 10,000 points each.
In the Moon Rabbit legend, the Moon Rabbit is seen pounding rice cakes (Korean version) or herbs/medicine (Chinese version) using a mortar and pestle. Therefore, the pet is a mortar and pestle.
If one looks carefully at the moon surface at night, there is the shape of a rabbit and a mortar on the surface.
This is the only time where LINE has caught up to Kakao Cookie Run in term of Pets - LINE would always be 2 to 3 Pets behind.
Unfortunately, it may be the last Pet to be released in either game, as at this time Kakao has not been releasing any new Pets for the last few months. This is likely due to spending more attention on their other game, Cookie Run: Ovenbreak.
