Kirby: Planet Robobot Cheats - 3DS

Ability Testing Area
After Beating Story Mode, defeating the Final Boss of Access Ark, and watching the Credits, the next you enter Story Mode, the game will show a message saying that you've unlocked the Ability Testing Area. While Kirby is in the Access Ark Hub, go to the right of Access Ark 6-2 to enter the Copy Ability Testing Room. The Ability Testing Area is an area filled with 2 sections that have all of the game's Copy Abilities. In the main area is a Metal Waddle Dee and some tiny Star Blocks that Kirby can use to practice his Copy Abilities. The second area there's a Robobot Armor, its Mode Abilities, some enemies, and hidden items. You can also come here to grab a particular Copy Ability, leave using the Warp Star, and keep it so that you use it for certain Stages. However, you can't take the Robobot Armor out of here.

Amiibo Powers
Every Smash Bros Amiibo (excluding 3rd party) can give Kirby a certain copy ability. With all other 3rd party Amiibo like Sonic or Pacman giving you a random ability. It should be noted that the Smash Bros Amiibos of Kirby characters are different than using the Kirby series Amiibo. With SSB Meta Knight and King Dedede giving you a random color change along with their power, while Kirby series Meta Knight, King Dedede, and Waddle Dee give the powers along with a color scheme matching the character. SSB Kirby gives you the Smash Ability, while Kirby series Kirby gives you UFO. This list has all the abilities granted from the Amiibo you can use. Note: Using Kirby Series Amiibo will also give you a Maxim Tomato and a random sticker each time you use them. Note: Mii Fighter Amiibo will either give you Sword, Fighter or Spark abilities.
