Grerks, Squurms & Water Greeps (Nelly The Monster Sitter)

Petronella Morton has an after school job that would give most kids a bad case of the night-lights! Because Nelly's not your average baby sitter - she's a monster sitter. And whether they're scaly, spiky, slimy, or furry, Nelly loves them all! But no one said monster sitting would be easy . . . When the Grerk's pedigree gog, Glog, runs away, can Nelly rescue him in time for the big Gog Show? After Slop the Squurm turns a game of hide and seek into a missing monster fiasco, will Nelly find him before his parents return? And can she catch a criminal with the help of three rascally Water Greeps? Or will her sneaky twin sister, Asti, get the last laugh?
