29. Fatman Is An Excellent Inline Skater (MGS2)

Fatman is a boss in Metal Gear Solid 2, an expert in explosives who has threatened to blow your entire mission to smithereens. Raiden is tasked with stopping him, which seems like a pretty manageable task, except that Fatman zips around the arena on roller blades. He might be a gigantic ogre in a bomb suit, but he's as nimble as a ballerina while skating.
28. There Are Plastic Frogs All Over Soviet Jungles (MGS3)

MGS3 takes place in the jungles of the Soviet Union. As the player crawls through the brush, they might notice plastic, cartoon frogs striking a proud pose in inconspicuous areas. When shot, they make a chirping sound that alerts all nearby enemies to Big Boss' position. They're a part of a minigame, and if every single frog is shot (including the ones during a sniping sequence on the back of a motorcycle, ugh), the player receives a special rank at the end of the game. Consequently, I did that and completed my 100% trophy run on the PS3. Whee!
27. Gekkos Make Animal Noises (MGS4)

Gekkos are 60-feet tall, bipedal, highly-dextrous assault robots that are deployed in combat situations. They're armed with a machine gun, a whip-like tongue meant for piercing and constricting, and an entire cadre of rockets. They're a terrifying presence on any battlefield, but luckily, the player can usually hear them coming, because they communicate by making barnyard animal noises. That's right. You could be holed up in a bombed-out hut and suddenly hear a deafening "MOOOO!" reverberating throughout the battlefield. No, that's not the signal that the petting zoo is open; it's your cue to run like crazy!
