1 Jane Goodall: I’ve had second thoughts about stitching together body parts to create a composite human being.
2 Terry: Oh, good. That was always a bad idea.
3 Jane Goodall: I’ve got a much better idea.
4 Jane Goodall: We can try stitching together animals to make hybrid creatures, like chimeras or hippogriffs!
4 Terry: Holy Hagrids!

Some might argue that the plural of chimera should be chimerae, but that usage is much less common and chimeras is preferred in every dictionary and style guide I could find.

Similarly for Hagrids over Hagriadae.
