When Jim runs through the jungle laughing and shouting with glee, the other animals are very concerned. This isn't the grumpy Jim they know. Soon Norman diagnoses Jim with a bad case of spring fever and tells Jim that he needs to find a cure. The other jungle animals offer suggestions. Take a calming breath! Sniff lavender! Take a nap! Try a time-out! Jim tries everything to get his grump back, but when nothing works, it becomes contagious and the other animals catch spring fever too. Soon the jungle erupts into a silly celebration of springtime as they all join in the fun.
