It appears there is no red Long Feather, as even Volcanic is just dark purple.
Please add one somehow.

Btw it's a bit lame QQQ Slime Lockbox is the only one that still drops, but it doesn't give any of the special colored boxes. Therefore those colors are unobtainable now as costumes can't be unbound. People like me, who have only one part of some sets, can't complete them. That's a bit sad.

Oh and Promissory Note and Tortoguns are basically useless now. To get Tortoguns, players need to be very advanced, but what they recieve is worse than all the weapons they already have.
