Have you ever looked at the Bulbapedia article that shows the ENGLISH Beta names of Gen I Pokemon? Well, most of these names are weird (in my opinion), like Arbok's is "Nagaasp", like seriously? That sounds like what a Indian Pokemon name would be (not being racist at all, just these beta names are weird). And Jigglypuff's beta name is seriously PUDDING, that sounds to gross and odd at the same time (same with Wigglytuff's, its CUSTARD). And Tentacool's is "Jilly"...? And Tentacruel's is "Man O War"...? Incase you didn't know, Cubone's is "Orphon"..so sad. But the actual interesting ones are Koffing and Weezing's, Koffing's is "Ny" (reflecting the polluted area's name, New York), and Weezing's is "La" (reflecting the name of Los Angles, which is still very polluted). Tangela's is "Meduza/Medusa" (Most likely "Medusa"). So yeah, Gen I beta names are weird.
