Camped at the Platypus Bush Camp, where we actually got to see platypus in the wild.
I just had to check the plural of platypus, and you can have platypus, or platypuses, platypi occurs but is etymologically incorrect, and platypodes, while technically correct, is even rarer than octopodes (octopi).
This information was provided in very long list of english plural forms which made me wish that I had never heard of home education. I mean, I think “English” is my best subject, and I have no knowledge of it at all.
