escaped medical leech

There are medical leeches!?

Yes! They work very hard to get their medical degrees. 

not this one, though. this one’s trying to ditch class. 

what was the class, color theory?

WHY THE HIFL WOULD YOU HIDE THIS IN THE TAGS!?

Also important to note they're not random leaches found outside obviously. They're "sterile" or as sterile as an animal can be, bred in specific environments and kept clean in the lab.
