Don't Open the Monster Blood

Don't Open the Monster Blood is a short story featured in the collection The Time We Ran Away. It was published in 2017.

Plot
Eddie and his sister Maggie are excited at the arrival of his Grandpa Hugh, as he is always joking around and gives great presents. It's almost Eddie's eleventh birthday, and he has brought a box labeled Monster Blood. However, Hugh warns the kids not to open the box. Maggie is tempted and convinces Eddie to open it, just to take it a peek. Upon opening it, they see there is just a little green ball. The ball soon starts growing, and it gets stuck to Maggie when she touches it. The Monster Blood starts covering her, and Eddie calls Hugh to ask for help. He scolds Eddie for not obeying him, but he tells him there are instructions that say how to stop it.

The substance has now become a blob, and starts reaching Eddie. He looks in the box and picks up a slip of paper as the blood begins to smother him. However, the paper only says that if you want instructions, you must write to Monster Blood Inc, listing the address, which is in Hadley, Missouri.
