Taurus Bathtub Curiosity?

[Liquefy]

I noticed something curious about the Taurus Bathtub: viewing it in the catalog, it sometimes appears to "glow" red (perhaps as if suggesting rage?).

First I view it as black with gold horns. Then when I "click" away (press down on the +Control) and back (press up on the +Control), I see the red "glow."

Back at my house, I can't seem to make the red "glow" appear.

Curious.
