Nimblebit has announced an upcoming Halloween update to the LEGO Tower mobile app
From October 15-31 2019, players will have access to a New Pumpkin Lift and New Pumpkin Lobby.
As part of the October update, the game has also been recently updated with characters and missions from the Hidden Side theme with J.B., Jack and Parker all integrated into the game as well as spooky minifigure pieces. We hear that the event will make those spooky minifigure pieces easier to get as well.
