易爆

易 = 勿 + 日 : Mnemonic symbol: a really easy puzzle consisting of only two parts.

Maud Younger (y) and the sun (日) are trying to complete a really easy puzzle (易) in the space station's bathroom (Ø4). It's not as easy as they thought though, because in zero gravity they can only move with the help of their bat wings (勿).

爆 = 暴 + 火 : Beelzebub (b) installed his newest addition to his little hell in the aorta's bathroon (ao4). There is an impressive fire (火) under a deep fat fryer which he will use to punish his clients in the most cruel (暴) way possible by deep-frying (爆) them.
