Platypuses or platypi?
when do you need an i. i looked it up and it said both are valid but i got some confident stubborn idiots to deal with and im a last word freak so i need some hard evidence on showing that im right and they are not. if you could send a link that would be nice. they say that both are valid but platypuses are not proper. platypi are. i do not agree i think both are valid
