"The simple text is easy enough for primary-grade readers, and it effectively captures the small bear's frustration and ultimate success. The soft, warm fall colors bring to life the bear's cozy home and surroundings, while touches of Halloween gloom give an appropriate punch to the story."

"The illustrations are cheerful, brightly colored,--simply charming--and they nicely underline the action of the storyline."

"Kovalski has a knack for depicting a safe, cozy environment of family and neighbourhood without being bland or condescending. Omar's weird expressions of disgruntlement as he tries out different costumes are funny and create character that goes beyond the usual trick-or-treating tale. At the same time, his ambitions and frustrations are utterly believable and true to his age (about 6) - all features that make this a satisfying picture book. Like its predecessors, this is a good early reader for those at about a Grade 2/3 reading level."
