Secret Seclusion

Secret Seclusion is the seventh, last and bonus island in Donkey Kong Country Tropical Freeze. The island is a few floating ruins and rocks, with lots of clouds around it. The island also unlocks Hard Mode once all three levels are completed and all mysterious relics are collected. This island is quite similar to the Golden Temple from Donkey Kong Country Returns. Each level is like a challenge, and it is a very ancient island. The island has only three main levels, until it unlocks Hard Mode.
