Magellan was angered by the amount of prisoners that escaped from Impel Down. He vowed to make sure that he'd bring back as many of them as possible. One plan of his was to make his poison even more potent, but he didn't know how. He tried to eat various foods laced with poisonous substances and the like. While they did work slightly, it ruined his stomach and digestive system completely. He knew it would be risky to take it even further but he decided to do it. However, his bad stomach was making a request. He fled to his personal toilet.
After a long battle with diarrhea, Magellan finished up. He noticed the pungent smell of his waste. Suddenly, a thought popped into his head. "What if I were to…No! That's going too far!" He disregarded the idea and flushed. However not too long after, he began to feel his stomach cramp again. He went into his toilet again. This time, looking at his waste, he took a small bag and collected it from the toilet. "Just this once." He thought. "If I mix it with other stuff, it won't taste too bad…right?" He sniffed the bag's contents; only showing even the Poison Man can be repulsed by his own concoction.
When lunchtime came, Magellan took the bag of poison shit and went into the kitchen. Upon grabbing a bowl he dumped the shit into it, mixing flour, sugar and other foods with it. He mixed the ingredients and formed a ball of purple-brownish goop. The shit was so powerful and pungent it rendered the other ingredients useless and tainted them, making the strong scent even stronger. It lingered into the kitchen, Magellan holding his nose in the process. "This is horrible." He said. "What do I do?" A voice was heard from outside. "It's no use. I'd better swallow this now." He did just that, chewing through the poison shit dough. Its sticky and manky texture stuck onto his sharp teeth, making his gums numb and painful. He began to feel sick just from chewing it. "This was a bad idea." He thought, chewing and holding his stomach. He finally ran out of the kitchen, knocking back the guard that was walking by. He went to his office and headed straight for the toilet and vomited inside of the bowl. The vomit being consisted of poisonous contents and agents only made the already horrid smell of the shit poison dough even worse. So horrible that Magellan fainted.
When he came to, he smelt the air around his office. It made him queasy, but he stayed conscious. Domino came in with a gas mask. "Magellan, it's time for-" She stopped, gagging. "Another battle with the toilet, I…" She fell, unconscious. Magellan thought for a moment. "If I were to…" He shook his head and flushed the toilet, but not before taking some of the poison shit dough vomit and putting it in a metal can. He smiled a little. "If it can knock her out with a gas mask, I may have found just what I've been looking for."
