Which McDonald's character promoted the chain's Chicken McNuggets after debuting in 1988?

The McNugget Buddies were McDonald's characters used to promote Chicken McNuggets after their debut in 1988.

They were anthropomorphic McNuggets created for advertising and promotional materials. Their stories and visual designs gave the product a cast of recognizable personalities rather than presenting the nuggets only as menu items.

The characters belonged to a later phase of McDonald's product-focused branding. Earlier campaigns had relied heavily on Ronald McDonald and the wider McDonaldland cast, while the McNugget Buddies connected character design directly to one product line.

They should not be confused with Birdie the Early Bird, whose role centered on breakfast, or with the generic term “Chicken McNugget.” The question asks for the name of the promotional character group.
