Elmo and Telly are reading the book Fascinating Facts About Insects. First they see two ants, and after looking at them through their magnifying glass, they learn that ants never sleep. Next they see two ladybugs and learn that ladybugs smell with their feet. When a butterfly flutters in, they wonder where his friends are and worry that he is lonely. Elmo decides to pretend to be a butterfly so he will have a friend, but the butterfly won't come over to Elmo. Telly checks the book and learns that butterflies go through a metamorphosis, or a big change, which is made up of 4 stages-starting as an egg and changing into a caterpillar then a chrysalis and finally a butterfly. Maybe if Elmo pretends to go through the four stages, the butterfly will think Elmo is a butterfly and be his friend. It works and the butterfly flutters over and lands on Elmo. They head over to Hooper's for a snack, and after checking their book, they learn that butterflies actually drink nectar from flowers or juice from fruit. Chris prepares them a snack of sliced oranges and they watch the butterfly drink with his proboscis, which is a curly little thing that unrolls and becomes like a straw that he drinks through. As Elmo begins drawing a picture of his new friend, Chris explains that he is a Monach butterfly. All of a sudden lots more Monarch butterflies flutter in and Telly checks the book and explains that Monarch butterflies migrate, or move, when the seasons change. The weather is just too cold on Sesame Street in the winter. Elmo is sad that his friend is leaving, but he will always have his picture to remember him by.
