Little dolphin Elvis is having fun, playing and knows for sure that everyone loves him - his mom, his dad, and his big brother. He is quite happy with the fact that he is the youngest, and therefore he is not at all happy about the appearance of his sister. Why is everyone running around with her? Why should he, Elvis, share parental attention and love with her? Why is it needed at all, it would have been better without it? So, dad and mom don’t love him anymore and they don’t need him?.. There are so many questions that it’s very difficult for the little dolphin to find answers to on his own... How good it is that he is surrounded by kind and sympathetic friends who will help Elvis deal with his questions and understand that being an older brother is also very interesting!
