What the subject says. Or if you other sites that use the same sort of pies/cakes

anyone?

That's going back a bit. There are a few trailers still floating around for their old membership site.

They are still available but from one of EuroWAM's partners TheWAMOutlet

https://wamoutlet.com/videos.php?search=Pie&scatid=0

It's also available from eurowam.net site. You have to filter by "Messy" or "WAMPlace".

Then browse from the last page and up as those videos are old.

Or poke the store owner. Maybe he could add a wam4fun tag on those videos.
