Tugs (1989)

The Stars and the Z-Stacks are both competing for a big steel contract. the fleet which can transport the most steel in one day, wins the contract. The canal is a short cut through Bigg City but Big Mac of the Stars decides to go round the bay and let Zebedee and Zak of the Z-Stacks take the short cut through the canal. At first Warrior of the Stars is confused by Big Mac's idea for both of them to go round the bay, but as you'll see the short cut through the canal wasn't necessarily the best route.
