This must be Tuesday. Lilo is going for a swim in the ocean and feeding her fish friend Pudge a peanut butter sandwich before heading to hula class. She believes Pudge controls the weather, and by giving him a sandwich she hopes for nice and sunny weather.

This piece of fan art was requested by someone at pixiv. I modified it a little to make it safe to post at this site.
Lilo and Pudge belong to Disney.
