The Cryptid Club

"The Cryptid Club has found its next case. There is strange writing on the bathroom stalls, and someone has stolen all the paper and pens. When a monster starts popping up in every toilet around the school and the principal is forced to close all the bathrooms, Lily, Henry, Oliver, and Ernie must solve the mystery of the Loch Ness monster before the whole school can't hold it in any longer!"--OCLC.
