Seal Block
From Starfy Wiki
Seal Blocks (Japanese: ふういんブロック) are red blocks that appear to have Ogura's face on them. They only appear in Densetsu no Starfy. They are found in every stage, and lead to a door that takes Starfy to a hidden place, often where a Treasure Box can be found.
Seal Blocks can only be destroyed with a Star Spin after Starfy defeats Ogura for the first time and accesses a stage again through the Stage Select. The demo glitch can also be used to access the Stage Select before beating Ogura.
Trivia
- If the player uses cheats to enter a door through a Seal Block before accessing the stage through the Stage Select, the room will be different.
