Sorry :( not good with photos but I can provide a link: PetSafe Healthy Pet Water Station, Dog and Cat Water System with Stainless Steel Bowl, Large, 320 Oz. https://www.amazon.com/dp/B002RT8M9I/ref=cm_sw_r_cp_api_i_B6YR3YWK1DSKGMC3W1PW?_encoding=UTF8&psc=1
I also have a bowl flipper. I ended up buying this in the smallest size. The 64 oz one is too heavy and squat for my 4lb mini rex to kick over. I would imagine that the 320oz version, which is designed to withstand a dog, would probably be able to hold up to your flemmie, as long as you keep it mostly full. If even that doesn't work, you could tie/wire it to the pen to hold it upright, since it has that convenient hourglass shape :)
Good luck!

I like that I can take the metal pan out, and clean really well. And I can fit my whole arm in the top, but it never gets dirty in there.
