Odyssey Pumpkin Poo is at least dominant to Whisper Sunset (and possibly Uber Odyssey). It's a bit of a wild trip to prove it all but here goes.
Proof that CoCo hides Whisper Sunset
(Coco showing Uber Ody vs Caleb showing Ody Tuscan Dream produces Whisper Sunset... btw Caleb is named that because he's part of my Ody Cosmos project, not because I think he's hiding Ody Cosmos XD )
Proof that Cream hides Ody Cosmos
(Redwald is Onyx hiding Brushed Steel, which pushed Ody Cosmos)
Proof that Roswell hides Ody Pumpkin Poo
(Cream threw Ody Cosmos, and the kitten wound up with OPP)
And that brings us around to Ody Pumpkin Poo being dominant (at least) to Whisper Sunset
Need to crack this kitty open and see whether it's Whisper Sunset or Uber Ody hiding.
