Panel 1: The Mane Six found a tar pit. Twilight Sparkle and Applejack are curious, Fluttershy is worried, Rarity is disgusted, and Rainbow Dash and Pinkie Pie are interested.

Panel 2: The Mane Six decided to step into the tar pit. It seems they're all enjoying it while sinking slowly into it, even if a couple of them won't admit their enjoyment...

Panel 3: The Mane Six have started to sink deeper, until only their foreheads remain above the surface. At this point, they're all enjoying the sticky feeling of the tar below, clinging onto their bodies. It won't be long before they go completely under...

Panel 4: The Mane Six have sunk completely under the tar, and now the only thing left of their presence is the bubbles rippling and popping above the surface.

Panel 5: After a few moments underneath the tar, the Mane Six resurface, gasping for air. They are now completely covered, coated, and plastered from head to hoof in the sticky black tar. But it actually feels nice to them, and it's kinda like a spa. Although they know that it'll be a pain in the flank to clean off and that their coats will probably be ruined and all messed up for a while, it was worth it. Plus they are having all fun in the pit of sticky goodness; even Rarity, who was initially disgusted, and Fluttershy, who was initially nervous. Sure, the six of them should probably be getting out to find a way to clean up the gunk; but for now, they're just going to stay in for a while to relax and enjoy the moment.
