The philosophical Muskrat is reading "The Uselessness of Everything" in his favorite spot, a hammock in the garden at Moominhouse, until he falls to the ground after a rope breaks. Embarrassed and restless, the next illustration shows him isolating at a beach cave where he is uninterrupted. Arabia Moomin mugs are crafted from porcelain and are microwave, oven, freezer, and dishwasher safe. The mugs have special details, like an identifying stamp on the bottom and attached gift tag with a sweet story about the design.

This one reads: "The Muskrat is an old philosopher. He reads dark, philosophical books and shares his pessimistic views with others. The Muskrat likes to spend time in the Moomin family's hammock, reading his favourite book. The worst thing he knows is to lose his dignity, which happens all too often in the Moominhouse."
