Bug-a-Booo ("Turma do Penadinho") is a Brazilian comic strip, created in 1963 and part of the Monica's Gang series.

However, their stories are not intended to be scary, they are sometimes classified as “Terrir”, which is a Portmanteau[1] of the Portuguese words "Terror" (horror) and "Rir" (to laugh).

In some of the stories, they have to deal with the fact that vampires, ghosts, zombies and mummies are no longer appreciated as characters of horror films.

[1] In 2015 a graphic novel based on the Bug-a-Booo characters entitled "Penadinho: Vida", was released as part of the Graphic MSP being made by Paulo Crumbim and Cristina Eiko.

Bug-a-Booo has also appeared in a few of the Monica Toy episodes, with one episode under the title Penadinho Toy, starring Bug-a-Booo, Skully, and Vic Vampire.
