The FBI arrives at the mansion, headed by Dale Grissom, where they try to piece together clues along with Bink's parents and his nanny, Gilbertine. Meanwhile, Bink, now outside on the ground and crawling about, finds another part of his book – the blue bus, which he then boards. The criminals realize he is escaping and start chasing the bus in their van, but their efforts are in vain. Meanwhile, on the bus, Bink crawls into the bag of an obese lady who gets off at her stop shortly afterwards. By the time the criminals catch the bus, they realize Bink is not on board and follow the lady, leading to an altercation after she catches them. In the distraction, Bink crawls up to a revolving door at the entrance to a department store and is forced inwards by its momentum. He is stopped by an employee who works for the store's day care center, believing he is another baby who escaped from there. He then escapes from the store and eventually crawls into traffic after a ride on a taxi. The criminals attempt to follow him, but keep getting injured in the process as he makes his way to the city zoo. They are shocked to find him in the ape house with a western lowland gorilla, which shows a maternal side and does not injure him. The criminals try to retrieve him, but the gorilla notices and pounds Veeko's hand, throws Norby into the air using a mop as a catapult, and hurls Eddie against the bars of the opposite cage after roaring loudly at him.
