Oh My Girl shared the teaser images for its rotational unit Oh My Girl Banhana’s first pop-up album, set to release at 6 p.m., Monday.

The jacket image of the first album, titled “Banana Allergy Monkey,” features singers HyoJung, Binnie and Arin in pastel floral outfits and tiaras. The addition of the comical monkey tail is easy to miss at first, but once noticed, becomes an image that sticks.

The three singers have shy, innocent smiles on their faces with mysterious monkey tails growing out of their backsides.

According to WM Entertainment, the group’s label, the song “Banana Allergy Monkey” is of electronic house genre that tells the story of a monkey who is allergic to bananas, who finds the solution in the alternative banana-flavored milk.

Oh My Girl Banhana will showcase the pop-up album on Tuesday at 1 p.m., through Lotte Home Shopping channel.
