When the snow around on the mountains surrounding Wartwood Swamp finally melted, Hop Pop Plantar decided it was time for Anne and his grandchildren to travel to Newtopia to find answers on how to get Anne back home. Anne and the Plantars used the Fwagon, with Bessie driving it, to travel through Amphibia in order to get to Newtopia. The trip lasted for weeks until Anne, Bessie, and the Plantars finally made it to Newtopia.
- The Fwagon is similar to Rapunzel's Caravan from Tangled: The Series.
- It also serves as Marcy's living quarters while she is staying in Wartwood.
- The term "Fwagon" was coined by Hop Pop.
