Gargantuan Vessel Assembly Yard

"Only the wealthiest, most determined and - let's be honest - heartless monkeys would build an assembly yard capable of building the monkeys most feared bloon type. The ZOMG. May the monkey god have mercy on us all! It's the best monkey building the game can offer!"

- Official BMC description

The , also known as the GVAY is a MvM building that is unlocked at level 25 in browser-based BMC and at level 27 BMC Mobile.

With the GVAY built, ZOMGs are unlocked for research in the Bloon Research Lab. In BMC Mobile the required $150,000 could be stored in bank combinations such as by using 10 banks (available at city level 27) upgraded to level 4 (unlocked at city level 25).

Trivia

 * Below the building, the floor looks like the sand in Desert terrain.
 * This fact is an exception on mobile, and is instead tarmac.
 * Despite the quote saying "It's the best monkey building the game can offer", DDTs can be researched too and thus contradicts the claim of "best monkey building the game can offer", except in the case of the mobile games, where DDTs cannot be researched.
 * Mathematically, the size should actually be 4x4 tiles since a ZOMG contains 4 BFBs, and the Oversize Airship Support Bay takes up 2x2 tiles.
 * It is one of the two buildings that take up 9 tiles of space; the other being the Temple Complex.
