Tin Can Wally

Worms 4: Mayhem
Tin Can Wally was a cowboy in the Wild West Theme, and a minor antagonist of story mode. He only appeared in the mission "Tin Can Wally". He challenges the player's team to a shootout (shooting random targets that appear in order to win), because Professor Worminkle wanted to take his gold which angered Tin Can Wally, but then the player wins the shootout and kills Tin Can Wally. He has two weapons, which are the Sniper Rifle and the Shotgun. He also has four sons (all of which try to exact revenge on the player after Tin Can Wally's defeat), and he seems to be a friend of Boggy the Kid.

Worms: Ultimate Mayhem
He is still the mini-boss of the Wild West Theme. He has the same role but he is more accurate in this game.

Trivia

 * There are two ways to fail in the mission: Either by running out of time while shooting the targets, or by killing Tin Can Wally during the shootout (the player's Worm kills him in the cutscene after the shootout ends).
 * The commentary panel also shows up when attacking Tin Can Wally himself, saying "You're supposed to shoot the targets not the Worm!".
 * In the cutscene after winning the shootout, the player's Worm "shoots" Tin Can Wally, killing him several seconds after. Right before his death, he tells the player's Worm "Wait... I can't take this secret to the grave. I am your fagh... Urgh...". He was obviously going to say "I am your father", which is a reference to Star Wars.
 * Sometimes if you shoot him away from the targets, he will Skip Go.
