They are Legos, as in "go clean up your legos"

They are not actually Legos. I think most English-speaking countries know this. "Go clean up your Lego", "get the Lego out", "made out of Lego", "playing with Lego".

“After you finish eating your Eggos, don’t forget to clean up your Legos”

In terms of Lego vs Legos I think they hate both.
