Brawl Yard
As the name says, it takes place in a yard, similar to the one in the Snagret Hole. A tured over bucket is in the middle of the area and it will give you shelter from the Decorated Cannon Beetles. There is also no Gatling Groink on the bucket. Other enemies: Cloaking Burrow-nits, Shearwigs and possibly a few Sheargrubs
There is also a neat, well, glitch, that let's you leave the border. Throw your Pikmin over the barrier, then walk to a DCB that is near the wall, attack it, and when it buckles, walk in front of it, and it might just throw you of the course. Grab your Pikmin and now you can take your friends marble from behind! You can't walk as far away as you want, though. There is an "invisible" barrier; you can also see were it is when you watch the rocks from the beetles.
