What’s your favorite experiment/toy

My personal favorite is yarnaby I just think he’s adorable, even when he opens his mouth and his head splits down the middle he’s still adorable, he is the perfect blend of creepy and cute. Also the way he’s cute until he opens his mouth reminds me of how in the first chapter huggy wuggy looked friendly until he opens his mouth revealing his sharp teeth, which is another reason why I love yarnaby
