Moan'ica is the older sister of Ghoulia Yelps, with whom she is on warm terms. Their parents both work for the Department of Monster Vehicles.
Moan'ica is one of the graduating students of Merston High and, due to her last name, the second to last to receive her diploma during the ceremony.
- Given that her name is only spelled out once, it is unclear if the apostrophe in the middle is meant to be there. For perspective, Nefera is named twice and both times her name is spelled "Nefra".
- Much like Minnie Taur, Moan'ica's sudden and short inclusion appears to be to not make Nefera de Nile's introduction stand out. Previously, Ghoulia had been identified as an only-child.
