Rosencrantz: When two will do, why just have one? Guildenstern: We're twins, you see, so two's more fun!
— Rosencrantz & Guildenstern, "Scooped"
Rosencrantz and Guildenstern are two mouse brothers who also happen to be twins. They live in a trailer owned by humans who happened to pass through the Great Forest, allowing them to meet Oyster and Slippery Jack. Rosencrantz is the mouse with grey fur and necktie while Guildenstern has brown fur and a bowtie.
Full of boundless energy, Rosencrantz and Guildenstern rarely sit still. Both are incredibly optimistic and carefree, living each day to the fullest without fear. They love to have fun and will jump at any opportunity to bust a rhyme or sing a song. They can be quite air-headed at times, but are experts when it comes to human objects.
Rosencrantz: "I'm Rosencrantz, he's Guildenstern." Guildenstern: "He speaks for me, as you will learn."
Rosencrantz: "They can't be twins, 'cuz she's a girl." Guildenstern: "Yes! she's a girl, and he's a... a what? A pearl? Earl? Whirl?" Rosencrantz: "Oh, knock it off, Guildenstern..."
Rosencrantz: "Now, I know you're scared and frightened..." Guildenstern: "And the Stompers have you down..." Rosencrantz: "But before you run away..." Guildenstern: "Take a chance to look around!"
Rosencrantz: "Our private exit." Guildenstern: "For members only." Rosencrantz: "In view of the situation, I pronounce you both, uh, temporary honorary rodents!" Guildenstern: "Welcome to the club!"
Rosencrantz: "Good luck, kids." Guildenstern: "It's been a slice!"
Compared to Rosencrantz, Guildenstern can sometimes have a bit more trouble coming up with rhymes.
