Another level has a wall of explosive barrels to your right, a wall of explosive barrels to your left, a wall of explosive barrels above you, and all of them make a cage of Explodium if you touch one the wrong way. The hint? Lol!
Putting hats on various creatures, upon which one will discover that a hat can be placed on each of the hydra's heads.
Try three LOLWUT's
Spawning a dapper or gentlemanly hydra will result in each head wearing a monocle and a top hat.
Spawning multiple opposite-colored Maxwells and leaving an item nearby. They constantly steal it from each other, eventually leading to the whole group fighting each other to the death over something as worthless as a ball.
In the sequel, if any baddie gives you trouble, try spawning an Indestructible Evil Baby.
Or Cannibalistic Guy, then Fattening Girl. You can guess the results.
Pregnant Medusa as well. Shortly after the kid is born, something gets petrified.
Vinesauce discovered that "pregnant baby" works. You can also ride on babies. "Giant Blue Pregnant Einstein" also works.
In one mission, you are required to unfreeze a child. Get a torch, and then grab the starite after freeing the kid. You set his school on fire due to having to hold one item at a time.
In one level, you are required to break open a piņata. One easy way to beat this level? Create a grenade and hurl it at the piņata. The party guests will all panic and run to safety, as the grenade blows up the piņata. There's a giant hole in the floor, but you accomplished your goal and no one died. Next level!
This one strays into Videogame Cruelty Potential, but one mission requires you to hydrate a man stranded in the desert. Give him poisoned water and he'll happily drink down the glass, hand over the starite then crumple up into a heap and die. You still win.
From the opening cutscene of Unlimited, we have this.◊ Particularly Lily's expression and the derpy smile of the wagon.
The "ScribbleQuest" challenge gives us a great one: after you've given the team their weapons, they fight off a dragon, who promptly kills everyone except the cleric. After she begrudgingly heals them, the team ditches their weapons and pull out bazookas.
The "Chef's Apprentice" challenge ends with you constructing a motorcycle for a biker dude...and the chef says "This is too cool to just give away! See ya!" and drives off with it.
In the "Merit Badge" challenge, you need to give a scout a projectile weapon so that he can shoot a target. His aim ends up being so bad that he shoots down a satellite, causing his instructor to freak out and grab the gun.
Note that a slingshot can also do this.
One of the missions in Listy Colon has you helping a pirate swab a duck.
Almost any mission involving projectiles can be solved with objects such as a rocket launcher and an RPG launcher. Carnival games? Feel free to blow your targets away! Just don't kill the person in the dunk tank.
There's a mission at Kana Craters that involves you attempting to help an arctic native hunt a space whale. If you give him a boat/other form of flying vehicle, the whale capsizes it and it falls back down in flames. If you give him a jetpack, however.... The whale eats him. And gets the "happy" emoticon afterwards.
Non-canon example, the object editor in the Wii U version. Make way for baby and chainsaw hybrids!
During a cutscene, when Maxwell and Hal Jordan start showing off how their powers are similar, Maxwell finishes off Hal's construct with a Fancy Plaid Colossal Cthulhu.
At the end of the Green Lantern vs. Sinestro mission, Sinestro knocks out Hal by hitting him with a giant train. He gets ready to attack Maxwell when the entire Green Lantern Corps show up.
Sinestro: This has escalated more quickly than I'd like.
Also the main conflict of the story level: Guess who takes the Starite and won't give it back? None other than Larfleeze. MINE!
When we first see the Green Lantern Corps fighting the Sinestro Corps, Guy Gardner can be seen relaxing in a folding chair while sending constructs to battle Maash and Lyssa Drak, saying "Just lemme know when you're ready to fight."
