Leonardo Hakase to Kirin-mura no Nakama desho: Halloween Party da yo Kirin-mura!

A special of Leonardo Hakase to Kirin-mura no Nakama desho focused on a Halloween party. This was a tie-in to a Halloween even the DLE Store was having, where one of the bonuses of coming to the event, was watching an event-only short. It was later included with the DVD release of the series.
