They are a little shiny which makes them slippery and they don't have edges that make stacking easier, they are all very sloping and will slide away from each other if you are not careful with each placement or your base is not very strong. They also need to put the right ones together to achieve some kind of balance (e.g. matching their tails very well). My son is not good at any of these things. Despite this, he loves to play with them. Like when you're playing a video game that you're really, really bad at, but you can't stop playing it. 10/10 for children who are very careful and well balanced or for children who are very patient.
