部 = 咅 + 阝 : Bruno Bear (bu) has been harassed by the Imperator (阝) in the space station's bathroom (Ø4), so Bruno sets up a trap. He creates two fake boobs (乳部) out of poo-poo (咅) and as the Imperator grabs his boobs, the Imperator realizes his mistake and exclaims "bah!" (部).

曲 = 囗 + 卄 : Mnemonic symbol: a harp. Cupid (qu) is playing a harp (曲) in the space station's living room (Ø3). He's sitting on a big enclosure (囗), playing the harp (曲) and wielding a double axe (卄) at the same time.
