The Sigrún was inspired by the bone flutes played by the Vikings. A number of these have been recovered from archaeological sites in Scandinavia and beyond. The Sigrún is made from PVC with a wooden 'fipple' and has three tone holes, so can be played with one hand. The scale is G pentatonic minor, but missing the F (G, Bb, C, D). However, by cupping the bell with your other hand, more notes can be obtained, such as the F. The Sigrún features a ribbon for carrying around your neck, but the cat and helmet are not included, sorry!
