T.S Spookytooth has been illustrating for many years. Throughout these years of brandishing a paintbrush, he has explored the diverse fields of children's picture books; magazine and newspaper illustrations; and advertising, packaging, and illustrating for websites.

When not working on illustration commissions, he likes to find time to work on many of his own personal projects. He keeps these projects locked in a suitcase but sometimes he forgets where he left the key. An ideal day for Mr. Spookytooth is to ponder and then to draw these ponderings. Some food is fitted in along the way followed by more ponderings and the occasional readjustment of his bow tie, but ponderings are the main order of the day.

He also lives in a house with Mrs. Spookytooth and thankfully she is fond of a ponder as well . . . and is good at finding lost keys.
