Is a DODO rare in Adopt Me?

I've been hearing a lot about the DODO pet in the popular game Adopt Me, and I'm curious about its rarity. Could you tell me, is the DODO considered a rare pet in the game? I've seen some players trading high-value items for it, so I'm wondering if it's truly hard to come by or if the hype is just building up its perceived value. Your insight would be greatly appreciated!
