Children's book by Perlink The Flying Unicorn by Sally Odgers Adele Kay Thomas

A funny story about Perlinka the unicorn, how she can easily learn to be charming. That spell is not always right and correct, so it gradually jumps into chaos, the signs begin to be useful. Having lit this book, the little readers find out how their best friends—veletka Olive and the firebird Tokh—can help her to believe her magical reality? And how will the battle between Perlinka and her friends with dirty grizzlies end? What will be more expensive for them - inimical and cute and ugly, always unsafe, which is important to get out of?
