オーシャンクリーチャーズパック

My 6-year-old builds sea creatures with these every night before bed, and the fins and tentacles bend into shapes regular blocks can't. The glow pieces actually charge up under a lamp and stay lit long enough for him to fall asleep holding one.

The glow-in-the-dark tentacles are the best part — my kids build sea monsters at bedtime and then turn off the lights to watch them glow. The magnets snap together tight enough that their creations don't fall apart when they carry them around.

Bought this for my 6-year-old who's obsessed with sharks, and the fins and tentacles snap together way easier than I expected for how bendy they are. We turn off the lights after bedtime stories and the glowing pieces make the whole ocean scene look like it's floating.
