A new impression of a possible layout in SketchUp.
Most notable changes: The dino and one long wall on the right side.
The two paddos are sacrificed to make room for a single dino. The changeable wall is removed in favor of one long (varied) wall on the right side and thus a lot more wall, creating a much bigger climbable surface! The cave is a bit reduced in size to be able to sit it front of it.
