Mackarther (マッカーさん, Makkā-san) is an animal in Curio's Shop whose body is in front of the shop's stairs.

Characteristics
Mackarther has the appearance similar to a slug, its body yellow and slithery, while its head is white with black beady eyes. It wears what appears to be a green army beret. In its mouth is a large, corncob pipe.

Hint
Mackarther loves to smoke, and it seems as though someone close by also does.

Trivia

 * Mackarther is a parody of Douglas MacArthur, an American five-star general who accomplished many things during his time, but namely lead the Allied occupation of Japan in 1945. This is not only apparent in its appearance and name ("Makkāsā" is the kana for "MacArthur"), but also in its description. His position's title was officially known as "Supreme Commander for the Allied Powers", but in Japan it was referred to as "General Headquarters" or "GHQ" for short. Thus, a full translation of the Japanese text would be, "Affects the mannerisms of the GHQ general".
