Toast bread slices and spread each with 1 tablespoon of peanut butter. Set 4 slices aside.
Slice banana and place 2 slices on 4 pieces of toast for the owl's eyes. Add a small dollop of peanut butter to the center of each banana and place a blueberry on top.
Quarter 1 strawberry lengthwise and use one slice for each owl's nose. Thinly slice another strawberry lengthwise and use 2 slices on each owl for the wings. Add some raisins between the wings for a feathery look (Dried cranberries work here, too!).
Serve each owl with yogurt, any remaining fruit, and the 4 remaining slices of toast.
