LEFT TUNNEL:
You send some Primpsk drones (Primpsks that you control) down the left tunnel, carrying infected fruit. They walk down the long, winding tunnel, until they reach a large cavern. Inside the cavern are around 23 armoured Primpsks, seven wagons pulled by large maggots, and 5 other Primpsk, who are clearly merchants. One of the armoured Primpsks attempts to talk with the Primpsk drones. Needless to say, you have no idea what the various sounds coming from its wings mean. What shall you do?
CENTRAL TUNNEL:
The Schoolbus,with a full set of Scuttlers, advances through the large, central tunnel. It meets a large company of Primpsk, who seem to be leading several large creatures. However, it is hard to catch sight of these creatures through the incredibly large hoard of Primpsks. The Primpsks begin to overwelm the drones through sheer weight of numbers, soon reaching the Schoolbus itself.
RIGHT TUNNEL:
Sadly, you can't find a close enough pool of water to flood the right tunnel. Still, you station several advanced scuttlers, to guard against any incoming Primpsks.
EDIT: DRONES
Advanced Scuttler: Stong, armoured, built to kill. Has incredibly fast, shrimp claws.
Scuttler: Armoured. Good all around. Shoots poison.
Gatherer: Make to collect and process DNA.
Light-bulb drone: Gives off light. Fast, but otherwise useless.
Scuttler Tank: Highly armoured. Not very fast.
Schoolbus: Carries crabs. Gives of light. Very large and heavily armoured.
