New to the Animal Crossing Universe, Flick is thought to be the replacement of Nat, a previous character who would run the Bug Off events in the game. He's a bright-red chameleon who visits your island on occasion. He's easy to spot, thanks to his bright-red body, as he walks around with his studded bug catching net that matches the rest of his bug-inspired emo outfit.

Unlike other characters who visit your island, Flick isn't selling anything. Instead, he'll buy bugs from you at a higher cost than Nook's Cranny will.

If you sell your bugs to Flick, he'll pay you one and a half times the price Timmy and Tommy will, making for a considerable increase in profits.

Flick will pay you 3,750 bells for a wasp (compared to Timmy and Tommy's price of 2,500 bells), while a tarantula will get you a whopping 12,000 bells. For reference, Timmy and Tommy only pay you 8,000 bells per — which is still significant, but an inventory full will land you a few hundred thousand bells.  

Besides the Bug Off event, it's unclear how often Flick comes to your island, but it looks to be with the same regularity that Saharah comes with her rugs and wallpapers.
