Wagomuland is an amusement park that opened in Skypiea during the two-year timeskip. It is a very popular place to visit. Its name, basis, and creation are due to Usopp introducing rubber bands to the Skypieans during his time there.
Wagomuland opened on Skypiea, and Amazon, Aisa, and Nola all became employees. Amazon took a job collecting the entrance fee (30,000,000), and Aisa became a cloud balloon vendor. Nola joined the park as part of the "Nola Bungee."
Usopp's statue at the entrance is misspelled as "Usop".
