Big Blob is a mini-boss that appears in Stage 7 of Virtual Boy Wario Land. It is found sleeping, blocking the way forward through the stage. It is immune to all of Wario's attacks. If the player tries to attack the Big Blob, it will only briefly open its eyes, and then fall back to sleep.
In order to defeat the Big Blob, Wario must break several blocks nearby to allow a Torny to enter the area. Once the enemy reaches the Big Blob, it will cause the Big Blob to quickly shrink (while wearing a sad expression on its face). Defeating the Big Blob will reveal a door to the next area. Once the Big Blob is defeated, it will not appear in the stage again unless the player begins a new save file.
