Friends-Dinosaurs. Swim

Each book in the "Friends-Dinosaurs" series tells about one day in the life of the Tyrannosaurus Rex Rasmus and his best friend Trim the Troodon. In the second book, the action takes place on the beach of Little Lake, where the entire Rex family has come to sunbathe due to the sunny weather. Trim calls Rasmus to swim, but he prefers to lie on the warm sand. Then, Rasmus's older brother Robin appears and, as usual, starts teasing and mocking. Then he challenges Rasmus and Trim to a swim to the island and back. This whole endeavor doesn't promise Rasmus anything good: to tell the truth, he is not a good swimmer, and there are also rumors about a sea monster that is supposedly seen in the lake. With a heavy heart, he accepts the challenge just to prove to his contrary brother that he is not a coward. No one doubts that Robin will win - he always wins. However, quite unexpectedly, Rasmus finds a defender, and Robin gets a good lesson.
