Panel from Slylock Fox, 12/19/21

I initially assumed the solution to this mystery would be animal fact based: bears really do eat salmon and raccoons really do eat lobsters, so the wolf would only get theatrically excited about oysters as part of his criminal middleman routine. But the “strongest alibi” bit truly gets into the Orwellian mindfuck that is life in Slylock’s Forest Kingdom, where you can be immediately found guilty not despite the fact that you have the most evidence pointing to your innocence but because of it! Please do not dwell on the litany of horrors Sly subjected this poor wolf to in order to “convince” him to confess, this is a comic for children.
