A 180 HP pudding will split into 2 x 90 HP 4d8 med puddings, which will split into 4 x 22 HP 2d8 small puddings, which will split into 8 x 5 HP d8 tiny puddings. The party will need to defeat 15 foes making AEO at the end very valuable. If you need to bump up the CR on this have some mini puddings already present at the start of the fight.
