Jimbe woke up and noticed the present next to him.
"Huh? What's this?" He said as he grabbed the present and examined the exterior.
There was a tag on the top that said. "To: Jinbe From: Robin". Jinbe smiled and opened the box, giddy about what could be inside. To his surprise, it was just Robin's armpits! Jinbe gasped.
