Edragon rubbed his increasingly round belly, nice and squishy. Edragon tried to walk but his limbs were starting to be overtaken by his body, so more of waddling. He opened his mouth and out came some bubbles. Now he's trying to blow a big bubble.

Your torso dose not grow while blowing bubbles out.
The bubble Potion was accidently invented while Edragon was trying to make some inflation type
