You need :

Bloon inflation factory

Bloon Research Lab

Then :

Sprint Track for pink/yellow (level 8)

Extreme temperature for black,white zebra (Level 9 or 10 idk

Lead propulsion (Level 10 or 11 idk)

Rubber repair nano-tek (11,allows regrow)

Camo modification den (12,allows camo)

Bloon compression tank (12,allows rainbow)

Bloon Kiln (13,allows ceramic.)

Blimp Construction Hangar (18,allows moab)

Oversize Airship support bay (22,allows BFB)

i... forgot what its called (27,allows ZOMG)

i also forgot what this is called (???,allows DDT,but only available in flash. For ddts in mobile,camo craziness in zomg attacks can often feature them aswell.)

When you place the building to unlock a specific bloon type,you still need to research it in the bloon lab.

You will need a total of 190 bloonstones in mobile to research all.
