Decomposition most likely.

The reanimation potion wasn't perfect, so I guess Babu simply reached a point where the Hydrangea leaves could no longer halt the degeneration.

Remember that Babu was already dead when he received the potion, unlike Rea who drank it while she was still alive.

So the rate of decay finally exceeded the potions reanimating effects.
