Three Giant Snakes

This unnamed trio of Giant Snakes were summoned during the Invasion of Konoha by numerous Sand and Sound Ninja, this was probably done due to it being very difficult for a single summoner to call them forth. It is presumed these snakes are loyal to Orochimaru and Otogakure to have been tasked with breaching the first defense lines of Konohagakure. One of these snakes was crushed by Jiraiya using Summoning: Food Cart Destroyer Technique.

Appearance
Each snake has a red scarf attached right at the base of their heads. Each are covered in tomoe, and have three tomoe on their forehead resembling the Cursed Seal of Heaven. In the anime, these snakes are merged together towards their tails. They were also extremely tall, towering over even Konohagakure's wall and several buildings.
