ds will be 6 in two weeks ( im getting old)
he has a pirate ship very similar to that from ELC a couple of years back. he absolutly loves it and despite being 2 or 3 years old he plays with it almost daily.
my top tip would be that when you put it together get some superglue and glue all the peices into place otherwose youwill forever have him runnign to you whinging that the masts have fallen out.
Mind you saying that i have also seen that castle (what a bargain) and have been considering this for his birthday this year.
