专 = 二 + ㇉ + ㇏ : In front of the anthill, the scientist and Julian Giant Squid are focused on one thing: Electrifying the wheelchair of the scientist. Deeply concentrated they connect a capacitor to the wheelchair, which indeed starts to move a little.

责 = 龶 + 贝 : Zorro and the crab started a party in the elevator's kitchen. They wear funny hats and have lots of booze, but they are responsible drinkers and know when they have had enough.
