Kodiak Frontier

Kodiak Frontier is one of the levels in Sonic Boom: Fire & Ice. It is a snowy evergreen forest-themed island with several remains of giant totems. Due to D-Fekt, the island's environment has been messed by the by-products from the mining operations on Ragna Rock, creating fire and ice elements.

Unga Bunga
In this level, the player encounters the level's boss Unga Bunga, a giant totem statue brought to life by D-Fekt. For this boss battle, the player controls Sonic and Amy.

In battle, Unga Bunga attacks with arm rolls and fire-engulfed claps. Hit its hands when they are vulnerable to inflict damage. Then, when Unga Bunga's arms get stuck in the ground, use Amy to turn them into pilars for Sonic to climb up to D-Fekt and hit him. After four hits, Unga Bunga will be defeated.
