The hermit crabs are small crabs that wear an empty gastropod shell on top of them. Their shells cover the most of their bodies, except for their small, yet prominent black eyes and small claws.
In Sonic Heroes, the hermit crabs only appear in Team Chaotix's version of Seaside Hill, where they serve key roles. Here, the Chaotix's client orders them to search for hermit crabs to test their investigation skills.
In gameplay, twenty hermit crabs can be found around Seaside Hill. The player can pick them up by just touching them. They mostly hide around, below or on top of the ruins in the stage, and are rarely seen ostensibly. For the normal mission in Seaside Hill, ten Hermit crabs are required to be collected to finish the mission, while the extra mission requires that all twenty Hermit crabs are collected.
Hermit crab locations
|Hermit crab #1||On the path after the stage begins, where one can see three rows of Rings side by side, fly over the ledge on the right to reach the first hermit crab on a platform on the cliffside.|
|Hermit crab #2||On the path after the stage's first triple loop, the player will find a hermit crab on top of a stone block.|
|Hermit crab #3||After reaching the first two Warp Flowers and going upward, break the stone block behind the Egg Pawn there and get the hermit crab underneath.|
|Hermit crab #4||Ahead of the third hermit crab, break the Wooden Containers on the left, then use the ramp to get to the platform on the other side. Bounce on the Wide Spring, and up on the cliff is a hermit crab.|
|Hermit crab #5||Ahead of the fourth hermit crab, fly up on top of the incoming left pillar, next to the stone blocking the path after the Egg Pawns to find the fifth hermit crab.|
|Hermit crab #6||After landing on the beach after passing through the triple loop, check the first pillar on the left to find the sixth hermit crab.|
|Hermit crab #7||Break the stone on top of the third right-side pillar on the same island as the sixth hermit crab and look underneath to find the seventh one. The player can fly from there to the platform on the right.|
|Hermit crab #8||Jump into the Cannon at the end of the island while in Flight Formation. The player will subsequently land on the platform with the ninth hermit crab.|
|Hermit crab #9||Get to the small stone platform with the Wooden Container in front of the two stone pillars. The player can reach it by either using the aforementioned Cannon while in Power Formation or jumping down on it from the top of the stone pillars. After the characters land, break the Wooden Container to get the hermit crab underneath it.|
|Hermit crab #10||On the incoming island, stand on top of the incline and push the large stone block near the palm tree with Vector to reveal the hermit crab underneath.|
|Hermit crab #11||The eleventh hermit crab is located on the main path in front of the three Dash Panels after the beach area on the island.|
|Hermit crab #12||After the second Check Point, fly up to the ledge on the left instead of going into the Bobsled and break the wooden box at the end to find the twelfth hermit crab.|
|Hermit crab #13||Follow the path after the latest hermit crab and jump into the incoming Cannon while in Power Formation and destroy the three stone blocks on the island to the left. Underneath the right one is the thirteenth hermit crab.|
|Hermit crab #14||After the third Check Point, approach the Warp Flower with Charmy as the leader and activate it. Jump inside the flower and the player will be warped to the matching flower. When the player emerge, the hermit crab will be there.|
|Hermit crab #15||Drop down below the Dash Rings encountered on the way to the beach. When the player reaches the stone block, push it with Vector to get the hermit crab underneath.|
|Hermit crab #16||A little ahead, push the right stone block on the beach area before the Cannon to get another hermit crab.|
|Hermit crab #17||Follow the path of Rings on the second part of the beach to get another hermit crab.|
|Hermit crab #18||On the second part of the beach, another hermit crab can be found on top of the fourth pillar and stone block.|
|Hermit crab #19||Run up the path near the Cannon on the second part of the beach and then fly up to the upper path. When the player reaches the large stone block, push it with Vector and get the hermit crab underneath it.|
|Hermit crab #20||Return to the Cannon on the second part of the beach and use it. Run down the path the characters land on and run across the Ramp to traverse the gap. Pass through the Rainbow Rings, then get the hermit crab in the center of the path below the Flappers.|
