Jolly Jumper has a hidden Bowling Alley, and if you can manage to get a strike (knock down all ten bowling pins) you are awarded with the "Strike!" achievement.
Jolly Jumper has been reversed, and edited, to create a Big Pack DLC track titled Smoke and Mirrors.
(Need Tutorial Section)
After the first checkpoint in Jolly Jumper, you will come to a large hole with a ramp in the approximate middle, if you just fall down the hole near the right hand edge, you will see the bowling pins that you must knock over.
Press the "Y" button to launch your rider off of the motorcycle towards the pins.
Knock them all down, and you will have completed the Midnight Bowling Event.
