Moose is a very accomplished puppeteer as we see here in episode 108.
The 'wipes', such as the blueberry wipe seen here in episode 108, were not seen in the first few shows, but they became an essential part of the stories as a way to show the passage of time that would be comprehensible to the young audience.
Not only does Moose love muffins, he is also a huge fan of blackberry jam, especially ON top of a blueberry muffin.
The orange striped chair design in Moose's living room in episode 108 is a direct match to a chair in his book living room.
Stephanie Duncker, the senior location designer for the "If You Give a Mouse a Cookie" series, was inspired by a science fair at her children's school when creating science fair location for episode 108.
