Noun: trouble, dilemma, conundrum; puzzle, riddle, brain-teaser.
Let’s translate the book title. Pupu Tupunan pulma might translate best as ”Pupu Tupuna’s conundrum” or ”Pupu Tupuna’s dilemma.” Pupu means ”bunny,” and Tupuna is the bunny’s name. Pupu Tupuna is a series of children’s books by Pirkko Koskimies.
In Pupu Tupunan pulma, Pupu Tupuna loses part of his tail while jumping over a barbed-wire fence and spends the book looking at other animal’s tails trying to figure out how to replace the missing part of his own tail only to find by the end of the book that it grows back.
