Started around 10 am and with steady potty and kitchen breaks managed to get to the end.
Author of the drawings is 
Whip, whip
Run me like a race horse
Pull me like a ripcord
Break me down and build me up
I wanna be the slip, slip
Word upon your lip, lip
Letter that you rip, rip
It is 7.30 pm now. The song that was on repeat through the day ... know it by heart now.
