How would you get out of a cardboard surrounded by a moat with only a live white rabbit and a blues harmonica?

1 rule: you cannot play an f# on the harmonica

I ran out of characters had to sacrifice box

Tear off a piece of cardboard - write "Help feed me and my poor rabit" on it and start playing the blues until the cops come and take you away for vagrancy.

Jump over the moat, then sell the rabbit and the harmonica to earn my fare home.

what do u mean cardboard. how would u get into a piece of cardboard in the first place? unless u mean cardboard...box?

how about you spit on the ox untill it gets moistened and break a hole through with the harmonika.. take the rabit and hold on to it.. push it towards the moat and then drop it in and wakj over it out...or if it jumps then both of you dont get wet

I would run up the scale and jump the moat on the back of the rabbit!
