Gem Launching Zombie

Gem Launching Zombies are zombies that are encountered on Moist Caves Night 8. They launch gems at your plants. This may make them seem like Catapult Zombies, but they are much stronger, and move closer to your brains while firing the crystals.

Strategy
The Gem Launching Zombie seems to be a hard one. What do you do? Here's one idea: Plant a Solar Panel! They can discharge the catapult, and this guy will continue to move without launching any crystal at you! An Umbrella Leaf is a good defense when the gem is about to land. A Spealunk cannot help you much, though.
