I am pretty weak in Lego, infact 'null' as i never played it , or used it....but looking at your pics and creative design made with it, I think it is a good especially when it comes to keep the kids engage. Not everyone are so good with it...and also with Frog, never ever tried to get closer, even when they are abundant in the rainy days.
I'm a big kid so I'm glad I have some Lego to mess around with. I don't think fun is the domain of kids, everyone is allowed to have fun, don't you think?
With frogs, I know some people get freaked out by them, this Lego one is harmless though. 🐸
