Mosston School parent Tracey Barnard baked 180 cupcakes last week and each one was decorated with an owl.
The school is celebrating 140 years of primary education in Whanganui and they marked the anniversary with a day of festivities.
An owl is depicted on the school crest with the motto "Dare to be Wise" but wise owls became early birds for the celebration on Friday.
The day started with a Puanga (Māori New Year) celebration from 7am and children shared breakfast with family members in their classrooms.
"Some parents worked to put a hāngī down early and we are planting a kōwhai tree after lunch," said principal Michelle Watson.
