Even while I am not into modern Lego that much, every now and than Lego comes up with a kit that forces me to sit on my hands. And sometimes I loose...
Kit 31088, a 3in1 Creator set proved to be too much for my self restraint.
Anglerfish with little fish, or a Shark with crab, or even a squid (not build). I liked it so much I cleared the letter-shelf in my writing desk, and now I have a deep sea tank. I even bought 2 sets... The little unlucky diver did not come with the set, and the small Ray I copied from another set.
