Gold Trophies:

In Hoppa Choppa,the trophy appears after you kill all the animals, including
the rabbits. In Something Fishy, the trophy comes when you swim through all
the rings at the bottom of the water.

In Penguin Playpen, you have to kill all the fish in the water. The trophy
will apear on a cliff. Get the bird and fly up to it.

In Rat-o-Matic, the trophy is on a crate outside. It's on fire, so get in a
fox and push one of the barrels nearby up near the crate. Then get in a rat
and lay two toxic mines(feces)next to the barrel. The barrel will explode
and stuff will come out, dousing the flame, then get a mouse, go up to the
nearby legde, and speed boost your way off the cliff at the trophy (it takes
a few tries).
