Inspired by the classic rhyming song, Sana, sana, colita de rana, that many American-Latino children grow up with, this book follows Tina in her quest to become an aspiring Mexican wrestler, alongside her plush sidekick, Mr. Frog. After she suffers a boo-boo, Tina is made fun of by her brother. Her ouchie makes her want to quit, but it is up to her to face her fear of being injured again, and just like the song encourages - no matter how bad things get, today or tomorrow will always be better!
