The sly feline hides its claws
Busy as a beaver
No room to swing a cat
Extremely reckless
Fluid; Ever-changing
Loitering about town
①Covering up something bad you did ②Trying to swipe something that isn't yours
Everyone and their mother; Every Tom, Dick and Harry
To act like butter wouldn't melt in your mouth
Mice are the agents of Daikokuten
To open a can of worms
fabrication
a large unruly mob
All the time; 24/7
Like shooting fish in a barrel
Up late and up early
Hold a grudge
Nirvana
serenity from enlightenment
Tone-deaf
to lick
Thorough; Meticulous
A shock
Persian silk tree
