The name is in keeping with a lineage of animal tools for ad hoc page manipulation in Firefox. First was Aardvark, then Platypus. https://github.com/dvogel/AardvarkDuex
I was an original early user of Aardvark. These tools have remained obscure, but with a cult following because they’re such a quick and easy way to rip up a page to your liking. They were the direct inspiration for modern browser dom selector tools.
For hairy edge cases, uBlock Origin’s element picker is the gold standard for manipulating pages.
