Harpflower

Harpflower (ハープ花, Hāpu hana) is a plant-like animal whose body is situated inside the Flower Shop. Flora will remark how she is attempting to care for it, but to no avail.

Characteristics
The Harpflower's main body takes on the form of a golden, tear-shaped lyre, with red pegs and a few strings. At the top, the ends of the lyre touch and curve out, appearing as red tipped antennae. Either side of the lyre are branches that look similar to palm leaves. The bottom of the body is supported by four green tentacles.

Translation Differences
The English localization describes the Harpflower as a "cranebird". In the original Japanese text, the word "tsuru" (ツル) is used, which is commonly used to refer to crane birdsー the kanji being "鶴". However, "tsuru" is also used to refer to "vines", the kanji being "蔓". Given the context, this is the likely meaning.

Hint
It's very likely that Harpflower will be playing its sad song somewhere. Flora knows it well.

Trivia

 * As mentioned above, "tsuru" can mean both "crane bird" and "vines". There's a third meaning to "tsuru", when written as "弦", refers to "strings" on an instrument. Which means the Harpflower being "tsuru" was an intended pun on "vines" and "strings".
 * On the original official website for Moon made in 1998, Harpflower’s flavor text was the following: "ハープのような花が奏でるメロディは、どこかもの悲しい. それはまるで、不条理に勇者に殺された悲しさを表現しているようでもある. ", which translates to, "A harp-like flower that plays a melody with an air of melancholy. It's as if it were expressing its sorrow over it's irrational murder at the hands of a hero."
