Wilkins

Wilkins is the titular protagonist of a series of commercials advertising Wilkin's Coffee.

Role in the Commercials
Wilkins loves to drink Wilkin's Coffee, which he strongly promotes. He was a perpetually smiling frog-like creature who was accompanied by Wontkins, his more dour counterpart. Throughout the series of commercials, Wilkins tries to offer Wontkins a cup of Wilkin's Coffee, which he grumpily rebuffs. In retaliation, Wilkins would either maim, assault, or kill Wontkins; there are a few moments in which Wontkins would admit that he did like Wilkins' Coffee.

Wilkins' name is a pun on the word "will," while Wontkins' name is a pun on "won't" meaning that they either would drink the coffee, or they won't. If you don't drink Wilkin's Coffee, it's expected for something bad to happen to you. However, what happens to Wontkins tends to change in each episode. If he were to say that he didn't like coffee, something bad would happen to him. At this point, Wontkins would try to outsmart Wilkins by professing his love for Wilkin's Coffee. Wilkins, however, would usually see through this facade, and he pummels him anyway. Alternatively, nothing would happen to Wontkins, or he could successfully outsmart Wilkins.
