Avalon's Advanced Arament Academy is a level where Avalon teaches you how to use the RoboBun,the MechaPup, and the HamsterTron 2000. In the RoboBun part, Avalon teaches you how to do the Slam Attack (R1). Then, Avalon tests your skill by giving you 'test items'. There are some prize bubbles above them, so I would recommend getting them first, then slam attacking them. (Note there is an easier way to do it with 2 players. One player will jump on top of the other player and then jump off the other player's RoboBun.) Then Avalon teaches you how to use the MechaPup. He tells you to press R1 for Sonic Bark(used to push doors and other stuff open). (Note there is a part where you have to Sonic Bark to get some stairs over to the other side then do it again. If you have 2 players and the stairs are on the other side make sure you do not bark while player 2 is over there, causing them to get electrocuted). Finally, Avalon teaches you how to use the HamsterTron 2000. R1 is for boost or ' burrow with a bang! ' as Avalon calls it. Finally, you will have finished level 4-1 and will move on to 4-2 (Got the Hump).
Note if you have 2 players amd the other has the RoboBun, MechaPup, or HamsterTron 2000, don't touch theirs or you will get electrocuted.
