Timminz is an elder spokesman for the local Kobold tribe living in the vicinity of Wizard Norland's House of Many Ways. He appears to temporary caretaker Charmain Baker to follow up on a complaint about improper flower colors on the wizard's hydrangea bushes raised by the cranky, no-good kobold Rollo.
When Charmain refuses to let the kobolds cut the hydrangeas down, Timminz announces that there will be no more help from the Kobolds, and he and the rest of the tribe members vanish. But not before cutting most of the flowers off the bushes and leaving them on the ground below.
Charmain later meets Timminz again, but because she has helped to perform a service for them, things go better than they did before. Not bad people -- just stubborn as all get out.
