Within the game's data is an early low-detail model for Shipshape Island with substantial differences compared to the final version. Among other traits, the early model features a much different arrangement of pathways and tablelands, a different design for the Uni-Tree, whose roots arch over the ground and whose top features a cluster of leaves instead of an incandescent lightbulb, a much larger cannon adorned by a bird's nest instead of a telescope, and no cave in the ship's hull.
