Big always sleeps with his beloved stuffed T-Rex - and sings it a song at bedtime. Small is jealous of the attention that Big shows the toy and tries to make Big jealous by wanting a sleep-toy-thingie of his own. But what's that going to be? Big makes him a toy octopus but it doesn't hit the spot. Small tries a Frog but he just jumps back into the garden. He fills the bed with objects but none of them work because none of them make Big remotely jealous: all they do is keep Big awake! Eventually, Big realises what's really happening. He assures Small that T-Rex is only a toy - Small shouldn't be jealous because Small is more than a toy: he's Big's best friend. And with that Small relaxes and they can both go to sleep. Small is jealous of Big's T-Rex and goes looking for his own sleep-toy.
