19. On Level 121 (Perfect Match), there is a block with a patch of ice beneath. When solving the level, what is this block for?
From Quiz Old but Fun: "Chip's Challenge"
Answer:
Killing fireballs
The mystery of Level 121 is one that I would never have solved without help from the Internet. These are the situations: There are three sections in the level. One is the chamber in the middle of the level, which is inaccessible to Chip. One is the little strip of passageway around the chamber which Chip can move around. Finally, there is the strip of land leading to the exit, currently filled with fireballs. The fireballs are firing into the water, destroying them, but a nearby pink ball is relentlessly pouncing on a red clone button, making more fireballs. In front of the clone machine is a toggle wall. Figured it out yet? The idea is to close the toggle wall so no fireballs can be created. And the big problem is here: The fireballs in the chamber hit the green buttons in a way that Chip will not be able to make it to the exit before more fireballs are made. If you go to the bottom-right of Chip's passageway, where the hint block is, you can see two green buttons. The inner one gets pressed by two fireballs and the outer is attacked by one. Note that the green buttons are level with each other. Now you should loop to the top of the level. There is a red button that clones fireballs and the block. Here is where the puzzle unfurls:
The green buttons are level with each other. The fireballs on the inner area are not affected by Chip. However, the clone machine puts a fireball on the same path as the outer fireball. And here is the vital fact: The loop for the inner and outer section last the same amount of time. Now, press the red button when an `inner` fireball is on the single ice patch. If timed correctly, the machine should create an `outer` fireball that is level with the `inner` fireball. When the `inner` fireball romps the green button, the toggle wall changes. However, because there is a level `outer` fireball that presses the green button at the same time, the toggle wall WILL NOT CHANGE! Return to the top and repeat for the other `inner` fireball (it should be right behind/in front of the first fireball. Finally, you might make a mistake. This is where the block comes in. If you push the block down, it will slide across the ice, rebound off the wall and kill Chip. Ouch. However, if Chip pushes the block and immediately steps up, the block will come back, not affecting Chip. Useless, huh? But when an `outer` fireball that doesn't have an `inner` partner arrives close, push the block down and step up. If this is done at the right time, the fireball will hit the block and turn right, straight into the water. Use this to get rid of all waste `outer` fireballs, and if the bottom section is still raining fire, hit the green button on the left side of the level. Wait until all fireballs are gone, then follow the path and finish! Phew! (It's easier said than done. Yes, I'm serious).
