Catch kanga-rats is a mission in Jak 3. Kleiver requested Jak to use his leaper lizard to catch six kanga-rats that had been raiding his storeroom. In return, he would allow them to drive one of his buggies.
Completion of this mission in the PlayStation 3, PlayStation Vita, and PlayStation 4 versions of Jak 3 will unlock the bronze trophy I Smell A Rat.
Walkthrough[]
The first mission inside Spargus as well as the first time on a leaper lizard. This one has you running around a lot. There's a total of six kanga-rats (easy to find by using the map) scurrying around the place and they have to be caught with your mount.
Technically, they're all slightly faster than you are, so you're forced to use the leaper lizard's charge attack to cut the distance when close enough. To get close enough, however, one will need to cut corners and use the lizard's maneuverability to their advantage. A cutscene will commence automatically when a kanga-rat is hit, showing it being gobbled up by the leaper lizard.
It is technically possible to kill one with melee attacks. However, this means you need to corner one (preferably in the street leading to the Garage) and get close enough to force it to run past you to escape. Similarly, you can also rolljump after it and hit it with the Scatter Gun.
