There have been a lot of new objects introduced recently, (a good thing) but they leave some questions. First, what are their weight class? This especially applies to othe new objects that have special properties. Some are obvious, but some are not.
Also, at least one object needs to be identified. The X-Men starter set has an object that I have no idea what it is. It could be a blanket, it could be a giant slipper, or it could be vomit squeezed through a kaleidoscope. I can't tell. Can anyone enlighten me?

If you have the Danger Room set then you have the rulebook which explains special objects. For the special object tokens, the yellow bordered ones are light and the red bordered ones are heavy, just like that standard objects. The blue bordered ones are 'immobile' and can replace either light or heavy but there's no way to pick them up or move them around. As for the 3D objects, their weight classes are listed in the sets they come with.

As for this slipper blanket vomit... I have no idea what you're talking about. The Danger Room set comes with the power generator, which is a big metal and yellow cylinder, and the broken robot, which looks like a robot torso with a head and single arm. I can't picture either as a blanket or slipper.

Oh! Wait! Are you talking about that weird, reddish, wing-like object token? If so, I have no idea what it is, but it's a standard object, not a special one.

Its taken from one on the indoor parts of the non-sinister maps. That's all I remember.

So no one knows what that thing is. I'm also curious about the weight classes of the new objects in Collateral Damage. Is the Aerial Baffler a heavy or light object? What about the other objects?

Look @ the color of the ring on the Aerial Baffler card. Yellow=light, red=heavy, blue=immobile which can be either light or heavy.
