ANOTHER HOBBIT RIDDLE (ALSO FOUND IN SWEDEN)

This little riddle, similar to that of the Theban Sphinx, has not only been recorded in the Shire of Middle-Earth, but also in Sweden of all places. In fact, I first came upon this one as a kid in a Swedish joke book, NOT in Tolkien's legendarium. Maybe I will include both versions of the riddle in What Little Sandra Read at Twelve...
Again, if you give up... highlight below the riddle to find the answer!

(Hobbit version)

No-legs lay on one-leg,
two-legs sat near on three-legs,
four-legs got some.

---------------------------------------------------------------

(Swedish version)

No-legs lay on one-leg,
two-legs sat near on three-legs,
four-legs hopped up to two-legs and snatched no-legs.
Then two-legs seized three-legs and frightened four-legs.
And thus, two-legs got his no-legs back,
while four-legs got some of what was left. 

The answer to both riddles:
No-Legs: a fish
One-Leg: a cat perch, or a nightstand table
Two-Legs: a person
Three-Legs: a three-legged stool
Four-Legs: a cat
