Cueio

A webseries about little quadrupedal animals that have the ability to transform into antropomorphic fighting animals. The protagonist of the series is Cueio, a rude, cold, and serious rabbit who is later revealed to have amnesia and shares the spotlight with his friend Vaco (a sensitive bull), and a fat human with a childlike mentality referred only as Primo (Cousin) by Vaco. The earlier episodes are focused on comedy, however over time the series developed a more serious atmosphere with continuity. It is considered the most popular series created by Ronaldo and his first work of great recognition having debuted in 2013. Despite its success Ronaldo discontinued the series in 2015 as he found it too tiring and torturous to work on it to satisfy his audience.

However on June 16, 2019, a CGI reboot called Turma do Cueio was released with its own YouTube channel. Unlike the previous series, the new series chose to focus on a more childish audience with cute and colorful visuals and no dialogue, in addition to the characters having their personalities changed focusing only in slapstick comedy. This reboot had a mixed reception, being disliked by most of the old audience due to the excessive changes.

The classic Cueio returned in 2026 on the Ronaldo Souza Channel. But it's not animation, it's storyboards. In this one, the story takes place after Cueio defeats his shadow/Depression, and now they are going to the tournament, in the clouds. And they meet new characters.
