Mango Thief

The Mango Thief leader is a robber that steals mangos. But he is also shown to steal TVs, dogs, people, etc. He seems to have a very large belly with his head tilted back. He has a robber mask on to conceal his identity. He appears in mango thief and nine one one. He reappears again in 1,000,000

Possible mistaken Identity:
Given that two other Mango Thieves appear at the end of Nine One One it is possible that he was not the burglar depicted in the episode at all, but rather that many Berds which turn to robbery happen to look like this.
