The common theme between my 3 concepts is animals with long arms because growing up, I love tying those parts together like ropes and hitting others with those arms.
The suckers on the tenticles will be LED lightbulbs.
The legs will each have a LED light strip inside and the body will have fading soft LED glow.
The chimpanzee’s arms will be long enough to hug behind the neck of a child. The magnets at the end will keep them together. The lightbulbs will outline the felt heart, flashing as if the heart is beating.
