That distant temple must be where the Orange Lanterns’ power source is kept! Grapple the vines near the starting point from a distance. If you get too close, the vines shut. Pull them apart so you can advance to the right. When you reach a dead-end, grapple the tall stone pillar on your left to pull it down and create a bridge.
Head upstairs after crossing the fallen pillar. Keep going until several Orange Construct Warriors activate a forcefield that keeps you at bay. Tag to Solomon Grundy and destroy the trees to the left to uncover a swampy spot. Burrow beneath the surface with Solomon Grundy, and he pops up with a water cannon.
Use the water cannon to hose down the stone blocks near the edge of the forcefield where a cracked wall is revealed. Use Solomon Grundy’s great strength to smash it, sending a chunk of rock flying into the constructs’ forcefield generator and destroying it.
Entering the Temple
With the forcefield down, advance and battle more Orange Construct Warriors. The temple door is just ahead, but those that can’t fly can’t reach it. Smash the plants in the background to uncover an orange hook. Grapple the hook and yank out a set of stairs that leads up to the door.
The temple door is covered by three thick vines, which must be removed. The first one’s easy—just grapple and pull the yellow flower off the door to get rid of the first vine. Go left and locate a big tree. Use ranged attacks to bring down all of its branches and then build a Lantern pad out of the bricks. Use the Lantern pad to construct a giant chainsaw that mows down the tree, exposing a blue flower. Grapple and pull the flower to get rid of the second vine.
The third flower is over on the right bank, but rushing rapids make the trek impossible without flight. Blast the plant in the river with a ranged attack to make it open into a platform that Batman, Robin, and Solomon Grundy can use to cross over.
Head to the right bank to discover another swampy spot for Solomon Grundy, who pulls a missile launcher out of the ground. Just what sort of temple is this, anyway?! Step on the button to fire missiles at the rocks atop the waterfall, exposing the final flower. Fly up close, land, and grapple its hook to remove the third and final vine. Return to the stone door to find some hopping bricks on the floor nearby. They must have dropped when the vines retracted! Build the bricks into a spinner, then push the green side of the handle until the temple door fully opens. Good work; now hurry through!
