Several people have found this one in the Research thread 1: "Using the wall climbing ability, slide Sophia [vertically into a one-block gap], then press jump [fast enough] so that you hover and, as the hover makes you go horizontally, you end up in the ground. Good times." http://www.explodingrabbit.com/forum/threads/bug-research-discussion.7/page-33#post-155338 2: "Bouncy Pits must be enabled. Use sophia to go down into a 1-block-sized pit (smallest one). Get to the bottom. Then sophia will be clamped and will float under the ground until it meets a pit of at least "2 blocks" in size. Interesting is that it moves to the opposite side, i.e. you press Right and it floats to left, you press Left and it floats to right. It's also possible to finish in that way (only in level 8-1, which has such pits near the finish). Once you cross the finish line while being underground, sophia will jump very high, and the flag on the pole will go down by itself. Funny" http://www.explodingrabbit.com/forum/threads/bug-research-discussion.7/page-33#post-159980 Video Reproduction 1: Video Reproduction 2: Credit to Rey D and StepS for helping to document this.
