Using Aviva’s newest invention, the Butterflier XT, Chris and Martin miniaturize, and then embark on the Monarch butterfly’s 2,000 mile migration to their secret forests in Mexico and investigate this creature's unusual life cycle.
Tropes:
- Chasing a Butterfly: A variation in which Chris and Martin chase after Maxilla on the Butterflier XT, partly to study and record the monarch migration and life cycle, but also because Martin wishes to aid her if she gets into trouble.
- Pretty Butterflies: Monarch Butterflies are certainly no exception. Unfortunately, Donita Donata also takes notice of them and decides to make them into butterfly barrettes.
- Visual Pun: When the Kratt Brothers activate their butterfly power disc, Chris initially ends up in Chrysalis Note mode.
- Vomit Indiscretion Shot: A Tree Swallow is shown spitting up a small black blob, to illustrate how predators learn not to prey on bad-tasting Monarch Butterflies.
- Wrong Turn at Albuquerque: Dabio and Donita somehow wind up on an iceberg while trying to drive to Mexico in search of the secret butterfly forest.
