What cartoon are these stills from? I found them on the Spongebob Wikia.

They're from a Hungarian cartoon called "A kockásfülű nyúl", specifically the episode "Kriszta, az indián". In the U.S., "A kockásfülű nyúl" aired on Nick as part of Pinwheel (the Pinwheel Wikipedia page lists it as Bunny in the Suitcase, but I don't know if that's the actual English title, as the actual translation is "The rabbit with checkered ears").
