During the 2010s, the Brazilian CN brought us some cartoons of dubious quality. Some were watchable, but others were a complete atrocity. Oswaldo was one of the worst Brazilian shows that CN has ever premiered. The art style is VERY UGLY and unoriginal (the creators simply imitated of the American cartoons made by CN), by the way the characters are very annoying and one-dimensional. What bothers the most is that the worst and most irritating character in the show is the title protagonist, Oswaldo, and his design is not very original either, it looks like a little monster from a Mario game mixed with one of the penguins from Adventure Time. It's the kind of show I wouldn't advise anyone to watch.
