Motion-Sensing Spider

My grandson spent hours building and tinkering with it.  Loves it ?? 

My son loves it. Easy to understand directions. All the kids that come over love it too!

Assisting my Halloween-loving eight year old while he built his motion-sensing spider (he named it Fizzy) was a blast. This is one of my favorite crates that we've done so far, and we've been a KiwiCo family for a couple years now. ?️❤️

So much fun! My 9 year old loved the spooky spider . Only negative would be that it doesn’t stay on the wall long.  I don’t know if it’s the constant drop and recoil, but unfortunately, we had to leave it down after multiple attempts. 

We loved this project and the quality is great. It can be used next year too!

This one was so much fun! One of our favorite crates so far!

Instructions are easy to follow and this thing is so much fun!

Really nice great product. I’ve build it together with my five year old daughter. It was really great described and good to do.
