The mission starts off with Bubby ordering the Protagonist to pick up a blue Mundano that Crazy Jimmy has dumped in northeast Park and take it to Dulli in West Park. After dropping off the Mundano, The Protagonist is given instructions to answer a phone outside the West Park Subway, and then to pick up a cab that is in an alleyway in southeast Island City for a bank job that Jimmy is pulling off. The Protagonist then has to pick Jimmy up outside the bank in south Park and take him to Bubby's love nest in south Island Heights.
The player is awarded 80,000 points (80,000 x Score Multiplier) and a +1 increase of score multiplier for successfully completing the mission.
Not chronological, this is the first mission in the GTA series.
After picking up Jimmy at the bank, there is much less risk in driving to the nearest respray shop in SW Park than rushing to the garage of Bubby's love nest. It's much closer, and there are no roadblocks either, probably you won't see any police cars on the way. (It can happen that the taxi is painted light green at the respray shop.)
