Archer actually asked for the Scribblenauts version of Pikachu holding a portal gun. I went astray somehow and ended up with a more "realistic" creature...although realistic is perhaps not exactly the right word...but it's not very Scribblenaut like anyway.
I'll have to admit my complete ignorance of the Portal game. I wasn't even certain which was the business end of the gun. Meanwhile, Pikachu became far more malevolent looking than I had intended.
