A ladder is a tool that allows Blockheads to climb up or down faster once placed. Ladders can be removed by tapping on them. Removing the ladder a Blockhead is holding onto when there is nothing else nearby to grab is the only verified way to fall other than doing the same with blocks. Flowing water will dislodge a placed ladder, dropping it as a loose item.
Where Found
Ladders are made in batches of 10, and can be made at the woodwork bench. Each batch of 10 ladders takes one wood.
