[6] In an interview with Music Feeds' Riley Fitzgerland, Dave Novak referenced the album title and bar saying "It was the place you ended up when you had a massive night and you wanted to forget all your worries and do stupid stuff".

Finlayson said "Reminiscent of The Colour and the Shape-era Foo Fighters and Death from Above 1979, Iguana will be an easy sell for anyone who likes a good fuzz-tone or a blown-out larynx.

"[7] Dylan Marshall from The AU Review called it "a blistering debut album" saying "Coming in at twelve tracks and forty-five minutes long, Iguana is a massive step forward for Polish Club.

It foreshadows bigger things to come.."[8] Harry Webber from Life Without Andy said the album is "Full of classic PC riffery, huge vocal hooks, and danceable rhythms, and sees the duo masterfully walk that line between polished indie-pop and head banging rock.
