The Reopening Disaster

When the exhibits at New York's Natural History Museum start behaving strangely, Larry and (Y/n) Daley and now the directors of nighttime operations must find out the cause. They learn that the Tablet, which magically brings Teddy Roosevelt, Jedediah, and the other exhibits to life at night, has started to decay. Larry and (Y/n) along with their son, daughter and museum friends, must travel to London's British Museum to learn how to prevent the Tablet's magic from disappearing.
