In the interest of making as much of a one-stop-shop as possible apart from collectibles, I've compiled all 28 achievements that aren't related to the two big sets of collectibles into one video.
After getting Boulder of Death, lick the boulder and carry it over to the corn field where the car is doing donuts. Place it in the car's path so that it crashes into the boulder to unlock Dodge This.
These achievements can be seen starting at the 02:54
mark in the video below.
