The Librarian from the Black Lagoon (2017)

Synopsis

When the class plans to visit the library for the first time, the students prepare themselves for the worst -- a dark dungeon of rules and misery, run by creepy monster-like creatures who laminate children if they even whisper. Imagine their surprise when they are welcomed to a warm and friendly place, where a smiling librarian invites them to explore some of the fun and funny books they have to offer.
