Name of Ganesh's mount?

What is the name of the Hindu elephant god Ganesh’s mount? I know that it is a mouse. Thanks.

Mooshak

The mount of Ganesh is most commonly called Mooshika, “Little Hoarder”; and occasionally Mooshikam, Minjur or Akhu. Accounts vary as to whether “Mooshika” is a personal name or a descriptive term (“mousie” - really), and what sex he/she is, though male seems to be the more usual choice - some pictures show him complete with un-rattily tiny testicles. Accounts also vary as to whether Mooshika is a rat or a mouse (but then like the Romans Indians may well regard the ship rat as just a big mouse, which is pretty-much what it is); and, if a rat, whether he is a Norway, ship or bandicoot (large murines of genus Nesokia, not related to the marsupial bandicoots of Australia) rat. Some sources even say that the mount of Ganesh is more properly a shrew: but certainly it’s normally nowadays believed to be a rat, or sometimes a mouse.

(I suspect that there may be several variations by dialect.)

The Sanskrit word mushika means “mouse” or “rat”, and is the origin of the name of Ganesh’s mount. It’s a personal name in the sense that, say, “Mole” and “Rat” in The Wind in the Willows are personal names.
