For christmas I bought my son the HABA dancing eggs game which comes with 9 yellow rubber-like eggs. The game is clever and fun, my son LOVES eggs and all things eggs for some strange reason. The problem is the material those eggs are made from off-gases a powerful smell. It is like an unopened container of gasoline in your living room. I keep waiting for the smell to wear out but it is still going strong, such that I keep the eggs outside since they stink up any room they sit in. Can this possibly be normal? What are these things made from? They don’t smell safe. The fumes they produce smell noxious.

Any information you find would be helpful, i want to know if I should throw these out,

Thanks.
