Artist is @kkchenwei on Pinterest/Instagram. Lots of cute duck art there in the same style, if you like this. Their signature has been cropped out of this version.

Poor guy on the right is missing an eye.

Nice art. Is the one on the right a pirate without an eyepatch?

ps :
What also floats in water?
King Arthur: A duck!
