1.d4 Nf6 2.g4 is the Gibbins-Weidenhagen Gambit, recognized as such in the literature.  I suspect the "Bullfrog" tag comes from someone who couldn't spell the proper name.


You forgot Alekhines defense, Mokele Mbembe.


Missing the Dragon and Pelikan Sicilians.


Also, the Wolf Variation of the Ruy Lopez (1. e4 e5 2. Nf3 Nc6 3. Bb5 Nf6 4. O-O d6 5. d4 Bd7 6. Nc3 exd4) and the Queen's Gambit Declined (1. d4 d5 2. c4 e6 3. Nc3 Nf6 4. Bg5 Be7 5. e3 O-O 6. Nf3 Nbd7 7. Rc1 c6 8. Qc2 Ne4)

A jellyfish in Spanish.


The Bird and Bird variation of the Ruy.....(yes, I know, "Bird" was his name.)


Basman's "Creepy Crawly", alluding to insects....
