Maria is a frizzy haired lady who only appears once in the Mystery of the Map graphic novel as Jorge's mother.
A seemingly attentive mother, she is slightly cranky. Maria has frizzy hair and wears glasses. During her appearance in the comics, she wears a bright pink shirt.
In Mystery of the Map, Maria is found in the first few pages. Jorge, Oliver, and Mya are flying in a hot air balloon, with Maria in a separate balloon along with a pilot. Jorge leans out of his balloon and mocks a cow, to which Maria shouts "Jorge, behave!", and he replies "Sorry, ma!"
