The Mouseum is visited by a former celebrity Trekker, a friend of Professor Kat, whose portrait hangs in the hall of distinguished former members. Baroness Felina brings with her the pet turtle Tommy, adorned by a giant ruble brooch whom she refers to as her treasure. Mip volunteers to take care of the “treasure” and away they go through the portal on a slapstick game of catch me if you can around the world. When Mip returns with the turtle and brooch he discovers that it is Felina’s pet and friend, not the brooch, which is her most precious treasure.
