I used pole vault with air trick handstand, works wonders! Til I started losing all my money trying to attempt 2 flips with the launch... I hate groupies...
I used the plank on lvl 30. I threw it off balance by adding 1 wood, then adding the 2nd to throw it off balance again, then adding the last to poke the box.
