If you're talking about the 3 ending monsters u have to duck so that when his head shoots at you it misses, and when his mouth opens after that shoot your toxic blaster into it asap. Do that same exact method 3 times and it should die. same thing for the other 3 monsters, just try to avoid their guns and bombs.
If you don't defeat the three "hydra" bosses, you have a long climb facing you, including two with the "wing nut" you use by walking. It is much easier to beat the bosses.
If you have the Haunted House card from the Store, you can leave anytime, but you will be leaving the Mech in the underground. To get back to it later, enter the island and use the teleporter.

The monsters on Steamworks are all mutations of plants on the island. They took over the island after being altered in the Research labs (Production Zone) to the right of the Hub. You battle them at several locations on the island. (see related question)

For most of the monsters, you can use the weed-whacking attachment on your mech. If that doesn't work, shoot them with the toxic blaster attachment.

SPOILER WARNING: The citizens of Steamworks Island had to hide from the plant monsters that they created so they hid themselves in a hibernation area for 200 years. The path to their chamber is through the plant-covered annex at the far left of the Living Quarters area.
This is not an island currently being developed, and likely never was. Various "military equipment" such as the Mech Walker (Steamworks Island) and the robot monsters (Astro Knights Island) were probably the source of this speculation.
