Penadinho

Penadinho is a character from the Turma De Mônica subseries Turma De Penadinho. He made his debut appearance in 1963 in the Cebolinha comic strip. He was once a normal Mônican before he died. His friends are often supernatural entities.

Physical Appearance
Befitting his nature as a ghost, Penadinho has to wear a white sheet to reveal his presence. His true form is an invisible, sentient air mass that can at least exert pressure on objects, which allows him to wear the sheet in the first place.

Name
Penadinho is alternatively called Bug-a-booo in the English version of Turma De Mônica.
