Animals and their Tails

Kutu and Ki visit a wildlife sanctuary where Kutu admires the tails of various animals. Wishing for a tail, Kutu imagines having one like a lion, peacock, zebra, fox, or kangaroo. When his wish comes true, he struggles with the tails and realizes they are not as great as he imagined. Ultimately, Kutu learns to appreciate himself as he is, without needing a tail.

What was Kutu's final conclusion about being themselves?
