Bonus Rounds

1-1, section 3: Stand between the fourth and fifth totem poles and wait for the platform to appear.
1-3, section 2: Look for the key egg right on the ledge just before the dropping platform. Once you have the key the platform lifts you to a bonus level instead of dropping.
2-3, section 2: The key egg is on the stone section right after the "2" sign. After that, the third platform lifts you to the bonus level.
3-1, section 2: Pass the two frogs and jump down two more steps to a long flat area. Run around and toss your weapon around and eventually the platform leading to the bonus area will appear.
4-3, section 4: Jump to the third ice-tower, and jump to find the key egg. The next moving platform takes you to the bonus area.
5-1, section 1: The key egg is just before the cloud platforms, and the last cloud platform then takes you up to the bonus area.
6-2, section 1: Jump over the rolling boulder and then wait around for a little bit for the bonus platform to appear.
8-1, section 3: Stand in the area between the rock with the hidden pot and the egg with the eggplant inside.

Level select

Allow the game to reach the title screen, then reset the NES console. Then, press Right, Left, Right, Left, A, B, A, B when the title screen appears again for a level select. I have tried this it does not work it just starts me at 1-1. This does work on Adventure Island 2

Get 1000 points

Locate the red flower in level 1-4. Shoot the coyote that attacks from behind twice while jumping to display a power-up in the form of a Nintendo controller. Get the controller to collect 1000 points. You only have to shoot him once after you jump but you have to shoot him before you jump over him.

Continue

Just to the left of the Goal (G) sign in Stage 1-1, jump up and down to find the hidden egg. Step on the egg to pick up the Hudson's Bee. Once you have found the Bee, you can continue after losing your last life. To do this, hold any direction on the Control Pad and press Start when the game returns to the Title screen.
