Monster Blood (Blue) from "Goosebumps" by Agnes Garbowska

I haven't been able to get anything from Agnes in the last couple of years, but I made sure to get something from her on the last day of the show.

The blue version of Monster Blood was the last monster in the original 62 Goosebumps books, featured appropriately enough in "Monster Blood IV." The slime takes the form of weird, blue slug-like creatures that are constantly thirsty. They have razor sharp teeth to extract liquid from any and every source they can find, drink until they burst, and then multiple. And the more they multiply, the angrier and more vicious they become.
