Have wanted one of these for my almost two year old rottie for months, he loves puzzle toys but was finding it hard to choose one big enough for him, I settled on the spaceship and aliens. Was keeping it for his birthday next month but he found it the other night buried in a drawer and pulled it out. It was like he found hidden treasure! I had to hide it so he’d go to bed that night, first thing next day he went looking for it again. It’s been 5 days and he’s spent hours each day playing with it. I’ve been supervising him constantly as the aliens are small enough he could swallow if he wanted to, but he just loves squeaking them and tossing them in the air or getting me to chase him for them etc. He nudges me when it’s time to put them back in and he starts all over again. It’s really well made and the stitching really sturdy. Have no doubt it will last. Can’t wait to get him more now I know how much he enjoys it!
