坏账

坏 = 不 + 土 : In the airplane's bathroom, there is a clear sign that it is forbidden to enter the room with dirty feet. Helga Horse is quite spoiled though, so she enters right after she went to the muddy stables and spreads dirt all around.

账 = 贝 + 长 : The crab (贝) opened a bank account (账) at the James II of England's (zh) bank in the anglepod's bathroom (ang4), but the crab soon owns a lot of money to James II of England. One day James II of England has enough and confiscates the crab's longboard (长) to cover the debt.
