Thingumy and Bob are inseparable and almost always walk around hand-in-hand. They speak in such a strange way, that initially only Hemulen can get to the bottom of what they’re saying. Sniff thinks they speak some foreign language.
This tiny and curious duo likes to hide in cramped places – under rugs or in drawers. They’re always friendly towards each other, but when it comes to other people, they don’t always reveal what they’re up to.
In the book Finn Family Moomintroll, Thingumy and Bob steal Moominmamma’s handbag so that they can sleep in it, but they return it as soon as they realise how much she needs it. However, they aren’t so willing to give up the King’s Ruby that they take from the Groke.
Although Thingumy and Bob are identical twins, you can tell them apart, as Thingumy wears a red cap.
