In DinerTown Detective Agency, he appears as both an informant and suspect for multiple cases. This alarm will annoy customers waiting in the lot, so Karma has to 'covertly' kick the car to shut it off. Colin's convertible has an oversensitive alarm and may set off when parked. In Parking Dash, Colin does not directly cause noise disturbance himself his car does.

It is highly possible that he will cost the player a customer if they're not careful. During Endless Shift, his noise frequency can range from every 5 seconds to a grueling every 2 seconds. This can be a little annoying depending on which customers are currently sat by Colin. However a small precaution should be taken: if Colin's served whilst chattering, he will simply continue doing so once he's done eating/drinking, hence causing double noise disturbance. So if the player were to serve Colin and check him out quickly, they can prevent his noisy chatter. In the Cooking Dash series, the player may have an easier time dealing with him since his noise is set on a more loose timer. There's nothing to fear though since he continues to eat normal food. In Diner Dash: Seasonal Snack Pack, Colin appears as a vampire in the Crypt Café.

This mechanic continues to appear in future titles, shared with other customers such as the Teenagers. This disturbs other customers, especially Bernie the Bookworm. Unlike the Family, he's always noisy due to all the yakking he does on his cellphone, causing noise disturbance every 5 seconds. In his debut in Diner Dash 2, Colin was given a unique noise mechanic.
