Ham-Mer is a large robot with a large ham labeled "Mer."
Impressive Meat By-product Slam
Ham-Mers are semi-common enemies in the game, first seen in Jellyfish Fields. They are the second robot to be encountered by the player. Similar to the Fodder, a Ham-Mer will, upon spotting the player, wield its weapon and chase after them. Then, once the Ham-Mer is close enough to the player, it will slam the hammer down in an attempt to crush the player. The best way to avoid being slammed is to jump out of the Ham-Mer's way as it brings its hammer down. Ham-Mers, despite their large size, can be defeated in one hit, and are usually found alongside a large group of Fodders.
"Ham-Mer" is a play on the word "hammer."
Ham-Mer's weapon is a ham shaped like a hammer with the word "Mer" written on it, which is where the name originated from.
During encounters with the Ham-Mer, SpongeBob will say "Ham...Mer. *laughs* I get it!" However, if the player is playing as Patrick, Patrick will simply say "I don't get it," indicating that Patrick doesn't understand the play on words in the robot's name, however still acknowledges it as a joke.
