I went to Babelfish.
I started with:
The platypus is a strange animal, but I like it.
to Spanish
El platypus es un animal extraño, pero tengo gusto de él.
to French
Le platypus est un animal étrange, mais ai goût de de lui.
to Greek
platypus u extrao, pero tengo gusto l.
back to French
El platypus es un animal extraro, pero tengo gusto de jl.
to Italian (suuposedly)
El platypus ES extra6no pero tengo gusto de 3el
...back to English
Platypus is a strange animal, but I have taste of him

I kind of like that result!

Alas, Babelfish doesn’t really let you bounce between Language Families.
