Oh, perhaps like a slippery slide into a pool filled with mud. Shiny is somebody who always enjoys mud when the warmer month start and it gets rainy enough to find some muddy ponds. (-^.=.^-)

Bill and Danny using Ren cover her like she is a donut with all kinds of toppings just to have fun licking and having sex with Ren.

How about having Nancy, Mi Lee and Ren go through a fuck machine that strips them fully naked at the entrance of the machine, puts them through multiple messes coming from above and below through spray tubes all while they get fucked in their asses, mouths and pussies by not just robo tentacles that are cold to the touch but also latex tentacles built into the inside of the machine that also cover them in special aphrodisiac latex that makes them horny with each passing second and at the end of it, they come out of the machine feeling uber horny and ready for a long fuck session while covered in all the previous messes under the latex while their still naked underneath it all. The big kicker is that at the end of the machine, they see Emmy and Lord Aborinth naked and ready to fuck all three of them since it was THEIR idea the whole time and thought it would make for both a good show and a great time

Definitely a dunk tank that goes down into a pie, maybe for the lady/herm rhino as well? And playing in the pie after ;)

whats in the dunk tank?

Pie filling ;) with a crust on top.

Panda Ren Being Dommed By Mi Lee and April in a Mud Pit

Punishment huh? :3c

I'd definitely say a condiment gungefest in an empty pool for Ren, Mi Lee, & Tomu

Ketchup, Mustard, & Mayonnaise. X3

Here's one, although perhaps a bit complex.

Nancy, Emmy and Ren, all suspended upside down over a vat of tar, with sex toys stuffed in them, trying not to cum. As each of them cums though, they squirt all over themselves first, and then get dunked after (I'm sure that would leave Nancy quite desparate to hold out with all her fur at risk).

If you wanted to be even meaner, you could have an audience throwing pies at them to humiliate them further and egg them on.
