I need help finding the Farm Cow and the **** Mouse.     I know to go to the farm and the sewers but I can't find where in those areas to put the stuff to summon them out.  Do I have to be at a certain point in the game to get them or something?

Bell's actually kind of obvious. Maybe too obvious. There's a bell on the fence. Use the cowbell there.

 

The mouse is a bit more hidden. It's almost like he's behind a secret passage. Let's just say that there's some pipes that you can walk around you might not realize.

I saw that bell but it won't let me interact with it so I figured that wasn't it.  I've walked all around it with no interaction icon coming up and I can't shoot it so I dunno what to do with it.

Nvm, for some reason it finally let me touch the damn thing.

cant find the dam mouse =(

Mouse is in sewers. Its a tricky location. Its the place where you find one of the nuggets. The one in the jar..... A breakable wall to the left of the **** show.

I think it wasn't there, it is two levels above that location, on the only ladder that goes above in that section.

I could be wrong then lol

Not entirely positive, but some of the quests for Jimbo can't be completed until you reach a certain point in the main story quest.  The most obvious one is the Canadian Spider, but I think one of the sewer ones (the **** mouse) is also only reachable at a certain point.

Sewers needs the alien probe...

For the rest, not much, shrinking for some bonus loot though (and nagasaki fart for achievement/friend).

 

Sadly I didn't notice the path at the 'acid bath' till after the game was long finished... ugh... every battle was one-shottable though. Very tricky area-transition that one...
