You can also set items to look like single-frame monsters and the player model almost works too! (No textures) You could use this to make enemy-stautes (NPC's anyone?), decoys, and collectibles... gotta catch em all! Sadly I could not change the explosive barrel model, however you can use it's model as a replacement.
SCENE #3: Happy Birthday Bitterman! Basically it's the Black Hole Generator arranged in such a way it looks like one of those air-filled jungle gym castle thingies. It is rotating because I was having issues with guys getting stuck, probably from lack of space to move around in. (They still do though not as much) As a result you can stop the party by 'putting away' the fun... you'll see.
