In this short, both Chip and Dale have black noses instead of Dale having a red nose.
"Squatter's Rights" from 1946 is the first Mickey Mouse Cartoon after "Pluto and the Armadillo (1943)" from 1943, three years prior. It was also Mickey's first post-war appearance.
"Squatter's Rights" from 1946 is the first Mickey Mouse Cartoon since "Mr. Mouse Takes a Trip (1940)" from 1940 where Mickey has an earlier character design, instead of his experimental character design with the perspective ears that he had since the 1941 Mickey Mouse Cartoon "The Little Whirlwind (1941)". The last Cartoon featuring Mickey with this design is considered to be the 1943 Mickey Mouse Cartoon "Pluto and the Armadillo (1943)". However in that Cartoon it seems from the brief glimpses we get of Mickey's ears (since he wears a hat that fully covers his ears all throughout the Cartoon) that they are already changed back to his iconic moving ears. Another notable aspect is that he again has his tail, which was omitted with the experimental character design change.
"Squatter's Rights" from 1946 marks the second appearance of Chip and Dale, after the 1943 Pluto Cartoon "Private Pluto (1943)", three years prior. Just like in their first appearance they still have their designs resemble each other and their personalities alike, which first got changed in their next appearance in the 1947 Donald Duck Cartoon "Chip an' Dale (1947)", and was also their second Cartoon to be nominated for best "Short Subjects, Cartoon" at the 20th Academy Awards in 1948.
"Squatter's Rights" from 1946 was nominated for best "Short Subjects, Cartoons" in 1947 at the 19th Academy Awards. It is the sixth of ten Mickey Mouse Cartoons to be nominated in this category, and the third with his modern redesign. "Squatter's Rights" recycles animation and a scene from the 1939 Mickey Mouse Cartoon "The Pointer (1939)", which was the fourth Mickey Mouse Cartoon, as well as the first with his modern redesign, to be nominated for an Oscar in this category.
