The Sixth Doctor and Frobisher

Big Finish doesn’t often delve into the comics continuity. Basically, they try to make sure that nothing Big Finish does directly contradicts the comics or novels if they can avoid it, and if there’s a particularly interesting element from other media, Big Finish will use it. In this case, that element is Frobisher, a Whifferdill private detective, which means he’s a shape-shifter who for some reason likes to spend most of his time in the shape of a penguin. As you can imagine, that’s a tough conceit to pull off on audio, which is probably why Frobisher only appears in a few stories, most of them specials. I think Robert Jezek does a pretty good job of capturing Frobisher’s tone. Whether these stories deserve to be “canon,” I’ll leave to your judgment.
