The B-vore was made to show advanced behaviors. Hence the B in the name. It does this by changing how it reacts to light. Vores are usually made to do one thing, head toward light. However, this vore can change its behavior. It can be photo-anything, including neutral. It changes behavior based on obstacles in its path. If it is phototropic towards a lamp, and it runs into the lamp's base, then it become photoneutral, orbiting at a fixed distance either clockwise or counterclockwise. If it bumps into something again, it could become phototropic or photophobic.
