Damn you science! Conversation with my 5 year old

My 5 year old Xander was telling me about his day:

“Today we played zombies, big Oliver was the zombie, we shot him with arrows and he would fall down then get back up again. so we collected C-Bombs and threw them at him, he fell down and was destroyed so he went to science and science fixed him so he came back, so we shot him with arrows again.”
