幼蟲

幼 = 力 + 幺 : Mnemonic symbol: a kindergarten.

Maud Younger (y) is taking care of a kindergarten (幼) in the outhouse's bathroom (ou4). To keep the young (幼) children busy she plays blackjack with them, each time dealing a card by pressing a power button (力). To make life not too hard for them, she is exclusively dealing aces (幺).

虫 = 中 + 厶 : Chantal Chicken and a mosquito are taking part in a dart contest just inside the engine's kitchen. The dart board is hanging in the middle of the entrance, and Chantal and the mosquito are standing to the sides. Over each of them a large fake nose is hovering: the loser will be covered in grey goose as punishment.
