Plum has the ? picture if picked from symbol select screen. However, it has the Plum picture but no effect if picked from Credit Card Essence (likely applies to Credit Card too).

when will the penguin bug be fixed

Or not! Bluebird now gives +1 once per spin when adjacent to another bluebird, just not the full 2x boost

Had to sacrifice flavor for balance

Bluebird is blue
Bluebird like blue
Why no Bluebird like Bluebird?

You can individually disable the symbols you don't want using the in-game mod list. By default every modded symbol has a green check mark next to it - click on that to change it to a red X indicating that the symbol is disabled and will not appear outside the mod list. Just make sure you don't disable the entries for Oyster, Magic Key, Rain, or Sapphire because that will exempt them from Bluebird's effect (Ninja is hard-coded)

I just want bluebird :(

I like how you used the sus capsules mod when taking screens for this mod
