Mostafa the Camel is a camel who is owned by Aligra Nite. Upon speaking to him, he states that he was solving the problem of how to write his proof of the twin prime problem without thumbs before Aligra suddenly loaded granite rocks on him against his will.
- When asked "How are you?" he replies "I have a pain all down my left side", a reference to the 2005 film The Hitchhiker's Guide to the Galaxy.
- Mostafa's mathematical ability might be a reference to camels' affinity for mathematics in Terry Pratchett's Discworld series.
