Dustine (Cascuda in the original Brazilian version) is a recurring character in Monica's Gang.
She is Smudge's constant girlfriend (he has been shown flirting with other girls in some stories). She often complains about the mania of getting dirty and fear of water that her boyfriend has, dreaming that one day he will take a shower and get clean.
The curious thing is that she sometimes shows herself dirty like him, with similar cheek marks, to accompany him. When this happens, she does not seem to care about his issues.
