Sing his own song:
Le li ki no gen...when he wants to provoke his brother.
Si ke deng, si ke deng, si ke deng deng deng...his chinese new year song
Ayon man - iron man
He is like an Undo button in the house, everytime when we start tidying/cleaning up the house, he will immediate start throwing his toys around. When our house is in mess, he is one happy boy.
He has lots of imaginary friends and likes to pretend, especially on supermarket game.
