He's still alive. As it's been shown he's able to regenerative powers and can grow back parts of his body that have been destroyed.



And what has also been shown is that Toffee is actually missing on of his fingers.



So it's highly possible that Toffee purposefully cut off one of his fingers and stashed it away somewhere safe (I'm personally guessing his jacket since it survived the explosion without a single scratch). So that if Toffee were ever destroyed, he could grow back his entire body from just that one single finger! O_O
