Seaside Coast

Seaside Coast is the first area in Sonic Boom: Shattered Crystal. It is a tropical region on the coast side of Bygone Island and is where Team Sonic's residences are located. When Amy was kidnapped by Lyric, Sonic the Hedgehog came to Seaside Coast to gather his allies for the search for Amy.

Overview
Seaside Coast, like its name states, is a tropical coast near the ocean on Bygone Island where the residences of Team Sonic can be found. Due to having two levels, Seaside Coast's level layout comes in two variants.

In Seaside Beach, the level takes place on a sandy beach with a mountainous region bordering and/or mingling with the beach, several palm trees, a few bushes, clear rivers and thin waterfalls. A mild breeze can be seen shirring up some sand. There are also here a few large statues from the Ancients. Closer to the sea there can be seen some small islands with palm trees on them in the sea. Closer to the sea are also wooden scaffoldings and paths, and a few Bygone Island-styled huts. Fauna here includes dolphins (or sharks) and red crabs.

In Seaside Jungle, the level takes place further into the island, inside the jungle. Like Seaside Beach, Seaside Jungle is a slightly mountainous region with rivers, waterfalls and some ruins from the Ancients. Here however, the ground is covered in grass and blankets of moss, and tropical trees are everywhere. Deeper into the jungle, the jungle grows darker and denser, and has bioluminescent insects flying around.

Story
Having learned that Lyric the Last Ancient had kidnapped Amy, Sonic traveled all over Seaside Coast to gather his friends for a rescue mission. Enlisting Tails first, the fox made a program that could clean the files on Amy's broken AVA so they could find out where she had been. The duo then decided to recruit Sticks for the mission as well, despite fearing her reaction over having her BFF kidnapped.

When Tails (who was reluctantly elected to talk to Sticks) got through Sticks' paranoid ramblings, Sticks was left surprisingly excited over Amy's kidnaping. She then left to save Amy and make snake boots out of Lyric for her. However, her attempt at an impulse rescue was halted by Sonic, who convinced her to work together with him and Tails, after he helped get her boomerang out of a Buzzsaw. Tails then showed up with some cleaned files that revealed that Amy and Knuckles had been at the Scrapyard, making the trio head for that location.
