You better watch out for 5 Seconds of Summer because they are on the attack ... a banana attack!
For the past several days, the group have been posting 0:15 videos on their Instgaram account of a smiley-faced banana that happens to be on a mission to face-slap anyone in its path -- including One Direction's Niall Horan.
The 1D member took a bit of a face-beating thanks to that banana. Niall was slapped on the cheek and forehead before it moved on to its next victim.
In other videos, with the "Mission: Impossible" theme song playing in the background, the banana goes up to its target and hits them repeatedly in the face, which is, actually, pretty hysterical.
In one particluar clip, Calum attempts to take down the banana by taking a knife to it, but the "banana hero," otherwise known as Luke (who we believe is the mastermind behind this plan) saves the day by pretending to punch Calum in the face.
