Gamariki

is a male toad summon.

Appearance
Gamariki wears a large bow on his back and makeup which includes red lipstick, pink blush on his cheeks and eyeliner. All this gives him an effeminate appearance, making him the toad equivalent to a drag queen. He is light green in colour with purple eyes and yellow patterns all over his body. Curiously, he more closely resembles a frog than a toad.

Three-Tails Arc
After Naruto got discharged from the hospital, Jiraiya offered to train him again and they set off on a journey. Jiraiya wanted him to train in synchronizing techniques, and therefore summoned Gamariki. Gamariki and Jiraiya then proceed to show Naruto what a synchronizing jutsu is, and Gamariki and Naruto begin a synchronization exercise. After failing to get along with Gamariki and work on synchronization techniques, Naruto decided to summon Gamakichi and Gamatatsu to work on synchronization instead, knowing that he has worked well with them in the past. Naruto and Gamariki mutually dislike each other.

Konoha History Arc
After setting off to train with Jiraiya, Naruto was first trained to recognise and disperse genjutsu. In order to do this Jiraiya summoned Gamariki who used Genjutsu Kiss on him, sending him into a world of illusions. In attempting to release the genjutsu, Naruto unintentionally ended up releasing chakra much in the same manner as his Rasengan, knocking Gamariki into a canal and knocking him out. It was revealed that this was the reason the two dislike each other.

Trivia

 * Gamariki shows apparent affection for Jiraiya, calling him "Jira-chan." Jiraiya and Naruto tend to call him.
