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.
Only thing that shows up is instagram profile with 81 followers and 12 pictures. I doubt it is they official account
Nice art. Is the one on the right a pirate without an eyepatch?
ps :
What also floats in water?
King Arthur: A duck!
