In Sonic Battle, Tails' Workshop is separate from Tails' House, although both are located in Emerald Town. The lab contains a battle arena and a training area, as well as computers which fail in analyzing Emerl.
Tails' Workshop appears in Sonic Battle as his battle area when Emerl is chosen to train with him in the story mode. It also has a unique Virtual Training mode to truly test the Gizoid's abilities. The arena is almost entirely open, with only a few cylinders in the corners.
- Tails' Lab isn't an arena at all.
