Objective: Rescue 1 Citizen, Collect all Coins
Reward: 4 Coins, 20SP

Enter the nearest building and pick up the two Coins and the Zapper. You can now Zap Timber, so remove the blocks around you.

Now hop on over to the broken bridge and fill in the gap with Timber. Pick up the Coin by the Rocket.

Our pal Harry can't get to the ground, so colplete the steps with Timber to encourage him down. He'll then run to the Rocket, completing the level. For full completion, zip up to where he was and grab the final Coin.
