Lead Propulsion Lab

"Lead Bloons are paradoxical - they are heavy and armored, but can float like a regular Bloon. This special Lab enables research of this weird and crazy Bloon type."

- Official BMC description

"I believe that I can now re-create the powerful outer armor of the Lead Bloons. They will be slow and heavy, but in an MvM attack we can flatten an unwitting opponent. Shall I begin the research?"

- The "Lead Bloons" research goal description in BMC Mobile

The Lead Propulsion Lab is a building in Bloons Monkey City. It is required to research for Lead Bloons in the Bloon Research Lab. With it, players can send Lead Bloons against other players and add extra lead in their attacks at the cost of Bloonstones.
