ABC aka mongy, dizzy, bindi etc is different from ducksfoot. Dutch passion has a frisian duck (ducksfoot x frisian dew) with the leaf mutation and sannies also sells a duckfoot, they had ~5 packs 2 weeks ago but out of stock now it seems
i found this reddit thread from 3 years ago about someone trying to track it down and i don't think they were successful. it does include contact information for mongy who supposedly took over breeding it from an old australian couple who had discovered it.
i sent an e-mail to the alleged breeder of this strain asking for more information and hopefully purchase some seeds if they're available. i'll update you guys if he responds
edit 2: mongyman is still active on the ozstoners forum maybe one of you ozzy blokes can register and buddy up with him or source out another member who has the 'mongy madness'
