Thomas & Friends

In Big World! Big Adventures!, Thomas and Nia arrived at this harbour alongside Ace, to follow him through the Amazon Rainforest on his around-the-world trip. Sir Topham Hatt later visited the harbour in hopes of catching up to Thomas.

Thomas revisited the harbour in the twenty-third series and accidentally caused Cassia to knock some crates of mangoes off of a flatbed Gabriela was shunting which Gustavo ran into. Raul later challenged Thomas to various competitions here.
