Any way to disable the brown birthday cake?

I looked under ‘installed mods’ and nothing was listed, so I don’t know of a way to disable the appearance of the brown birthday cake underneath each TC. It looks like a cow pie to me, so I would prefer to remove it or disable it, is there a way? I don’t mean to be a grinch, and I hope those who like the birthday cake can keep seeing it if they want to.

Goto game options, there’s a checkbox to deactivate event cosmetics.
