Inside of Goku's boot, Gohan had to run to dodge the massive toes. He was forced in between the big toe and the second toe.

Gohan transformed into Super Sayian and flew anround the foot but the only way out was up the giant leg. Gohan crawled up the massive ankle and used the hairs as hand holds.

Goku didnt feel gohan crawling up his leg as he was busy crushing a country.

Gohan finally made it up the leg when he realised he was under Gokus balls. He had to crawl up the titanic balls. He finally reached Gokus chest and he flew out the sleeve.

Gohan fle to the machine and used it to shrink Goku and Goten and he made himselfe grow. He decided to leave the world for later and he put them in his huge boot. He told them to lick his feet clean or to be crushed beneath them.
