Description
With the gazogem as fuel, the proto-pack transforms into a super jet-pack. This enables flying higher and faster than with the proto-pack, as well as boarding from less shallow locations.
Role in Twinsen's adventure
Since the elevators to the Upper City were temporarily out of order, Twinsen was not able to meet Johnny Rocket at the Imperial Hotel. The only way there was via a small river, that was too high for the simple proto-pack. Fortunately enough for Twinsen, Baldino said he could improve his proto-pack with the little help of a can of gazogem. The super-jet-pack itself had no vital role thereafter, as in most places the simple proto-pack would have sufficed. However, Twinsen did find it handy at certain points in his adventure, for example at the Island of Celebration, when making his way to the rock crystal, or in the Island below the Celebration, going to the secret mosquibee hideout.
