中饱

中 = 丨 + 口 : Mnemonic symbol: a dart board, because you always try to hit the center.

Julian Giant Squid (zhu-) is throwing dinosaur bones (丨) as darts on a dart board in front of the engine ((e)ng1). To make it a bit more difficult he's throwing mandarins (口) into the air as well and skewers them up right in the center (中 is a mandarin skewered on a dinosaur bone) in mid flight with the dinosaur bones. He's still able to consistently hit the center (中) of the dart board.

饱 = 包 + 饣 : Whenever Beelzebub (b) is hungry, he can just pull a Chinese cruller (饣) from his magical colorful handbag (包). In the aorta (ao3), he pulls out one cruller after the other and eats until he is full (饱).
