It seems the manufacturers or ornament company is making a frequent error in thinking the pig sells big. No matter how popular she is on her own, when pegged with other Muppet characters she's usually the weakest seller.
For some reason, that's just the way it is.
People like Fozzie (and Gonzo for that matter). As strange as it sounds, they should have made more bears and short-packed the pig. However, that Piggy pose does look good. Can't tell from the picture - hope they didn't make her skinny!
