Blockmart is a Multiplayer Map introduced in the 8.2.1 Halloween update, along with the other map, named Pumpkin Island which has been removed in the 9.3.0 update.
Blockmart is a small grocery store that has been abandoned. There are cars, trucks, tanks, and more vehicles outside of it in the parking lot. While inside, you will find many isles that have been completely trashed and robbed. There is also a roof, which is possible to reach.
The map recommends players to get the Pumpkin Thrower or the Hellraiser as it is also shown on advertisements around the store.
In the left bathroom, you will see a skeleton in the last stall.
The store might resemble a place where survivors were during a zombie apocalypse since the store is completely trashed and there is blood on the walls.
There is a pumpkin face that resembles the moon, just like the one from Pumpkin Island.
The map may be a reference to Wal-Mart, which is a retail store chain based in the United States.
In the 12.6.0 update Halloween update, it was brought back with Pumpkin Island and Spooky Theme Park.
