The Riddle of the Blue-eyed Monster

In the School of Secret Powers, it seems that not a day goes by without adventures! Either lightning strikes the tree under which Axel, Lola, and their pets were sheltering from the rain, and they begin to understand each other's speech. Or suddenly a stroller with a charming baby appears by the gate. Where did he come from and what does the strange note lying next to him mean? One thing is for sure - from that moment on, the whole school, teachers and students, will be in an uproar because of this strange boy.
