團

团 = 囗 + 才 : Tommy Turtle inspects the super secret box that has arrived just inside anthill. He's not supposed to open it, but with his super X-ray vision ability, he can see that it is filled with balls and dumplings.

Mnemonic symbol: a plastic enclosure. Willy Walrus (w) is keeping frozen fish in an enclosure (囗) in the Eiffel Tower's kitchen (ei2).

专 = 二 + ㇉ + ㇏ : Let's say the expert is a scientist. Also, 专 reminds me a little bit of the wheelchair symbol. Thus I choose a scientist in a wheelchair as symbol for 专.

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.
