Lambo

Lambo (ランボ, Ranbo^?) is a fictional character in the anime and manga series Reborn! created by Akira Amano. In the series, Lambo is an infant assassin who goes to Japan to kill the hitman Reborn. Upon his failure, he starts to live with Reborn’s pupil, the future boss from the Vongola Mafia family Tsuna Sawada. As the series progresses, Lambo becomes one of Tsuna’s six Vongola guardians, The Guardian of Thunder, and has to confront various enemies from the Vongola despite his young age. When Lambo shoots himself with the Ten-Year Bazooka (10年バズーカ^?) from Bovino family, he transforms into his future self from 10 years later nicknamed “Adult Lambo” (大人ランボ^?).

Lambo dresses in a cow suit complete with a tail, and has a huge afro with horns on the sides of his head which gives him the appearance of a bison. – Wikipedia

I kneaded Lambo with a happy-go-lucky mood because that’s how he is, in the anime too. :) I think your mood goes into the clay that you make. I should have made him smaller but his afro just got bigger! :D
