|~ "Alcheristman and Bloonacleboy" BTD6 achievement description|
Small Bloon Option is a setting that was added in Version 12.0. It is unlocked after beating a secret achievement called "Alchermistman and Bloonacleboy". This can be revealed when a game is completed with 900,000+ damage from Bloon Master Alchemist in a single game before Round 100. Round 100 does not need to be completed with a 900,000+ BMA that had 900,000+ damage in order to unlock the achievement. Similarly to Big Bloon Option, the effect is purely visual, and it can be enabled on CHIMPS Mode. Enabling both options will simply cancel each other's effects out.
- Both the achievement's name and the description are clear references to the TV Show SpongeBob SquarePants. Specifically, the former is a reference to Mermaid Man and Barnacle Boy, while the latter is a reference to a quote in Mermaid Man and Barnacle Boy IV.
- However, the actual quote is more like this: "You got it set to 'M' for Mini, when it should be set to 'W' for Wumbo.
- ISAB got the achievement by getting 900,000+ damage from BMA in a single game. It can be seen on one his earlier Version 12.0 videos.
