Not stoobid, in fact. Springtrap cannot speak, yet Scraptrap magically can? Springtrap and Scraptrap have entirely different corpses inside, they don't have the same suits, and it's been confirmed that Springtrap can be replicated, seeing as he shows up in Frights. Scraptrap meanwhile has voice lines and knows Michael is the guard in his respective game.
Of course, all good theories have holes, I'm just choosing to interpret this information as such
