After Gamougg is threatened to be turned into an NFT. The only way for him to save his life is to get Retaw (Say Retaw backwards and it says water) from Threa he will have no choice but to travel to Threa and find out that the Slime Man had a brother, this guy is the opposite of his own brother and hes mad, but the only place with the Retaw he NEEDS is at Slime Man's brother's place. Now Gamougg must get the Retaw, or else.
