Such cute little ocean pigs! There are some interesting names for guinea pigs out there in different languages. My kids and I speak both English and French... in French they are called 'cochon d'Inde,' which translates into Indian pig (actually, literally 'pig of India.) Of course, as they aren't from India, this also makes no real sense as a name!
Our previous neighbor had a spanish nanny for her son at one point, and the nanny said that in her area of spain, they are called conejo de inca = rabbit of the inca. The french version seems like its the along the same lines, the native peoples of the americas are called indians so must be what its meaning.
I love finding out the names other countries have for guinea pigs. In my opinion, they all make more sense than the english term, i mean where does guinea come into anything lol.
