If i had a big yellow submarine i would get my whole junior class together and go on adventures. We could go anywhere we wanted. We could travel the 7 seas. We could go from country to country.if I had a yellow submarine you would never see me again I would always be out in my submarine traveling everywhere going everywhere I wanted to go and nobody to tell me I couldn't do it. I'd take people with me so I wasn't alone.my group and I would go on so many adventures we would not be able to pick a favorite there was so many
