High high is a funny activity enjoyed by koyukkuris, and, in a limited form, adult yukkuris alike. Since yukkuris are usually small, ground-dwelling creatures, they've have an unusal instinctual desire of flying, expressed by the ornate cries of happiness they let while lifted, like "It's like flying in the sky", or "[Insert Yukkuri Type] has the sky in its hands" or "[Insert Yukkuri Type] is like Mister Bird who flies in the sky", or at least raise their line of sight and see further than their small frames allow. In the wild, usually a parent Marisa may let its smaller offspring on the brim of its hat, enjoying the vantage point, whereas adult Yukkuri, if feeling playful an brave enough, may ride a U-Pack.
