Arthur is a penguin. He worries about all sorts of things, but mainly about Christmas. Will Santa get to the South Pole all the way from the North Pole? Will he be able to read Arthur's writing? Will he be able to get through so much snow? Single-parent dad is very reassuring even when waked in the night each time Arthur has a fresh worry. Christmas morning Arthur has stopped worrying and all is well. Charming illustrations, including some busy mice to look for.
