Jelly Serpent Cookie

Jelly Serpent Cookie (Korean: 꿈틀이 나가 쿠키, kkumteuri naga kuki, "Wriggling Naga Cookie") is an NPC Cookie that first appeared within Cookie Run: OvenBreak's Main Story in the first half of the Yogurt Dunes Escapade update. Jelly Serpent Cookie has a light green body with a dark green snake tail and Jelly Snake hair. They carry a golden spear and guard the Jelly Serpent Temple.

Story and Event Involvement
Jelly Serpent Cookie appears during GingerBrave's Tale of the Main Story of OvenBreak, specifically in the Jelly Serpent Temple segments, though they are spoken about in the previous segments. They threaten the Cookies entering the temple to leave or else be "pulverized into crumbs finer than the sands".

They continue to threaten the encroaching Cookies until they reach Jelly Serpent Cookie's place in the temple, where they are chained behind a door. They tell the Cookies that they should not touch the treasure or else be cursed as they were to be bound inside the temple for all eternity. The Cookies are surprised to see that the 'monster' guarding the temple is actually another Cookie. After Jelly Serpent Cookie tells them that they were trapped there after defending the treasure from thieves, the Cookies decide to help free them. However, Jelly Serpent Cookie does not trust them and refuses to remain still enough to let them break the chains. GingerBrave comes up with a plan to tire Jelly Serpent Cookie out by running in circles around them so they will stop moving long enough to free them.

The plan works, and Jelly Serpent Cookie becomes tired and stops attacking. Lilac Cookie breaks their chains and Jelly Serpent Cookie is freed. Jelly Serpent Cookie is grateful to the Cookies and as a reward offers them any treasure they want, to which Yogurt Cream Cookie responds asking to have the Naga's Heart. After GingerBright asks if Jelly Serpent Cookie is sure, they reply that they guard the temple, not its contents, and gives Yogurt Cream Cookie the treasure. They then ask what the rest of the cookies want, but cannot tell them anything about the City of Wizards or the compass when GingerBrave and GingerBright ask. Jelly Serpent Cookie still doesn't want them to leave empty-handed after saving their life, so they decide to gift the Cookies with Invocation Cards.
