A very reddish sword with a smiley face on it. Where does this weapon originated from?

I’ve seen it in skyrim, in ponies and in some dude cosplay but still unsure where its originated. Maybe you can tell me?

Edited:

After 4 years I found out that this weapon belongs to someone called Dave. Dave crafted this weapon by using an Excalibur + a red frog = Scarlet Ribbitar.

Who is Dave? Dave is a character from MS Paint Adventures which you can play it here.
