It's the battle of the dinosaurs - whose dinosaur is really the very best?When Joel and Olivia sit down to dinner with two of their favorite dinosaurs, Olivia can't help but point out that her dinosaur is better. Olivia's dinosaur can play the trumpet while riding her bike, and her house is in the shape of a rabbit. Her dinosaur can make her own jam, and she even eats electric eels. But Joel's dinosaur can swim like a shark, and his teeth sometimes glow in the dark. And he's really good at jumping and sliding on his knees, he has x-ray vision, and he's not afraid of bees. Of course, with so many impressive qualities, it's hard to say which dinosaur is really better, but things get even trickier when a third dinosaur joins them at the dinner table. What could be more fearsome than a dinosaur that once ate a volcano and wears slippers the color of rainbows?
