Advance on the conveyor belts, being careful not to fall into the gaps. After a short distance you will meet George Jetson, who will warn you about Dr. Butler and wish you the best of luck. After a few steps, you will come to an elevator. Get on it and the elevator will automatically take you upstair.
When you get off the elevator, a screen in front of you will light up and Dr. Butler will give you a sarcastic welcome. Proceed to the right on the conveyor belt. You will come to a point where there is a spiked piston that lowers at regular intervals, over a cavity with a barrel. You will have to move so that you don't touch the spikes and enter the cavity when the piston rises. Destroying a barrel will get you a cactus cooler, but you'll have to duck quickly to avoid getting hit by the spikes, which will lower again. Then when they get up, jump onto the next conveyor belt. You will arrive at another similar piston and the moves to follow are the same, even if here the conveyor belt moves in reverse. You will get another cactus cooler. Continue to get to a third piston. Repeat the process and this time you will get a heart. Proceed to the right, jump to overcome the flames (or use your wings) and enter the next elevator to go up to the upper level.
Proceed to the left. You will now have to overcome some gaps with flames. The gaps are very long, so you should use your wings. Otherwise, you will have to jump with maximum precision. Alternatively, you can use the hoppasaurus and jump onto the conveyor belts above to cross this area safely. Staying at the bottom though, you will find a barrel with a heart. Later, you can also get a bronto burger. Enter the elevator to go up to the next level.
Proceed to the right. Here you will find other pistons, which move upwards. You can cross them by moving fast or by jumping. Nothing difficult. If you stay on top of them anyway, it will be enough to duck to avoid getting hurt. Later you will have to jump on some conveyor belts suspended on the void. Pay attention to the last jump, which is longer than the others. If you fall, use your wings quickly. Enter the elevator on the right to go up again.
Now you'll have to grab onto a hook hanging from the ceiling to get through the flames unharmed. The hook will take you up to a conveyor belt. Go through it and hang on to another hook to get past other flames. Go back to the ground and continue to the left. You will encounter a walking cannon. It is a very tough enemy, it takes several hits (or a powerful attack) to destroy it. Luckily, it will be facing the opposite direction, so it can't shoot you and you can easily defeat it. Continue to enter another elevator.
On the next floor, you will have to walk on a conveyor belt, defeating some jumping enemies. Hitting them as you move is difficult, so be careful. Later you will encounter two more cannons the same as the one you saw before, but these will be facing you and will shoot you. Try to defeat the first one quickly, with a powerful attack, while you can get around the second by climbing the platform above it. This way, you can safely hit the cannon from behind. On the platform there is also a barrel with boomasaurus eggs. On the higher platform instead, you will find a heart. Proceeding to the left, at the bottom you will find two more barrels, with a heart and throwing axes. Take them and go back. Before getting on the elevator on the right, however, it may be advisable to repeatedly destroy the two cannons mentioned above, in order to accumulate as many coins as possible. In fact, they will be very useful to you shortly. Even if the two cannons are tough, you can actually hit them from behind without any problems. Finally, go up the elevator to reach the highest (and most difficult) area of the level.
Now you will find yourself at a very high altitude. Ahead of you are many narrow platforms suspended in the void. If you fall, use your wings immediately. In the barrels you will find a cactus cooler, a heart and boomasaurus eggs. You can then choose between a path above and one below. Following the upper path, you will come to a long conveyor belt. Spaceships will attack you, launching some rather insidious spring-loaded monsters. Try to destroy them without hurting yourself. At the bottom you will find two barrels, with a heart and an extra life. However, you will not be able to get on the lift, the access to which is located below. Go back, get to the edge of the conveyor belt and drop down. Try to land on one of the tiny platforms, if you can't, use your wings. Other spaceships will drop spring-loaded monsters, so be careful. Then continue to the right by jumping on the tiny platforms or using the wings, until you reach another conveyor belt. Go up the last elevator to finally reach Dr. Butler.
Boss[edit]
The final battle is divided into three phases. You will have to defeat Dr. Butler three times to finish the game and each time he will attack you in a different way. First, the evil scientist will attack you with a bazooka. You can easily avoid his attacks by crouching down. To get past it, you'll have to jump over it. It's not that easy, however a couple of powerful attacks or two boomasaurus eggs will be enough to take out his first weapon.
The doctor will limp over and attack you this time with a hopping robot. Approach to hit him, go under him when he jumps and after hitting him move away quickly to avoid his punch. Nothing too difficult. If you can charge some powerful attacks or have special weapons, you will soon have the upper hand. Note: there is a very simple way to destroy this second weapon. As soon as it appears, get in front of it and start hitting it wildly with the club, without stopping. The robot will not move from its position and its attacks will not harm you. Hit it until this second weapon explodes as well.
Heavily bruised, the doctor will then climb onto his final weapon, a huge tank. To defeat him, you will have to hit the windshield. Then get on the tracks (be careful not to get hit) and get as close as possible to the glass. A cannon on top of the tank will attack you by firing lasers. Most of the time, if you stay in this position, the laser will pass over you without hitting you. Sometimes, however, the laser may come straight at you, in these cases move quickly to the left. Between attacks, jump to hit the glass with the club, charging a powerful attack if you can. Timing is everything. If you still have coins, use as many boomasaurus eggs as you can. After a sufficient number of attacks or four boomasaurus eggs, the windshield will break. At this point, a single shot will be enough to destroy the tank and complete the game. The exhausted doctor will crawl away and you can watch the funny ending sequence. Congratulations!
