Timmis

Timmis, also referred to as Timmus, is the youngest son of Hendreary and Lupy, introduced in The Borrowers Afloat as a quiet, watchful, pale little boy. He is the only one in the family whom Arrietty grows close to. She tells him stories.

He reappears in The Borrowers Avenged, now very active and adventurous. He enjoys climbing around the church where his family now lives, and dyes his face brown with walnut juice so he can blend in with the carvings.
