Twitch was the first Underbiter I ever came in direct contact with. He was in my sock drawer, gnawing on my favourite pair of striped socks.
Twitch is curious and easily distracted by distant sounds, turning quickly to spot the source. You'll need to get your fingers stitched up if you make the mistake of touching his long, floppy ears.
Favourite foods include peanut butter and socks (but never together).
