Elinor, Olive, and Ari are happy to welcome new members to The Explorer's Club, but as more and more kids join, a big problem arises: their clubhouse isn't big enough to fit all the new Explorers! It's time for the Animal Town picnic, but Ari is growing impatient waiting for Ms. Llama's famous ketchup, which just won't come out of the bottle. Meanwhile, Elinor and her friends follow a bee to its hive and observe the honey-making process, where they discover that honey is goopier when it has less water in it.
