Firstly,  make a comfy place for bigfoot to live and make him feel at home. Additionally, feed him some grass, give him some fresh rain water that had fallen from the sky onto some leaves and give him a fresh bubble bath with soap and sponges. Next, dry him with a towl or maybe a cloth of some sort and brush his back with a hair brush so he has nice fluffy hair. In conclusion, let him watch some tv and chill and give him a blanket to make him warm and cosy. Also, give him a snack to eat so he doesnt die and give him a drink and then make his crib so he can sleep and have a dream about something. Finally, when hes in bed make some egg on toast because bigfoots love that and make him a cup of milk and when he wakes up he will be fresh for another day.
