The first gun you get is the banana gun this is useful because you can
jump with it and you can shoot in hard to reach places.

The second is the porridge gun, this is extremely useful for BLOCKING
MACHINES if doing this it may give you a tool or a zoo token that
unlocks special scenes from the wrong trousers and the snoozeatron!

The third and final called the turnip launcher is very heavy because
gromit can't jump with it and it can blow its way through padlocks and
many other things. Note: this is very useful for killing bad guys.
