Original Description:

a more finalized reference pic for Tidy Trails! This doesn’t really capture how big she is, though
Her cutie mark is three green stars, one big one and two small ones
her tank isn’t part of her, she just puts it on when it’s time to work. She can help out by putting other things on her back, but her main job is as a pump truck mare
if you don’t know what a pump truck is, it’s basically a giant shopvac on a truck that’s used to suck up liquid waste from things like septic tanks, grease traps, and other nasty places. It can be a dirty job sometimes, but she doesn’t mind
