I have four Offical Muses at the last count.  This is Iris. The 'Third' in line to the throne of Top Muse.

These are Amelia (Tan one) and Peabody (the Black one) they are sisters and jointly hold the position of Top Muse.

 This is Vir who is the young upstart and fourth in line to the throne, but is trying his hardest to move up the ranks. By showing his versatility, patience, and charisma even under the most trying circumstances.
