190! I feel like I developed a pretty good strategy for keeping my Flubbies alive. Ignore the speed upgrade card, that makes Flubbies spread out too far from one another. ALWAYS prioritize Flubby Goo above all other cards, as this will maximize your damage output against Grunkas. In the early game, Boom cards should be ignored entirely. Loop between Spikes and Shell cards, adding Offspring after those are maxed out. At this point you should have a Mass of slow-moving Flubbies, use Healing cards to keep them grouped together and maximize the benefits of every card.
