the whole thing, they are generally carved from pine so they go up like kindling. My brother was over at someones house there once and saw a 4 ft one go up in about 30 second when somebody opened the door too quickly and the flames got fanned over and caught some extra fluffy carved sheep on fire... then the whole thin went up

Yes this looks like it is made from a light wood and with all the varnish and all I am sure you are correct in how fast it would burn to the ground
The 4 footer might be just the one we need for a proper playmobil transformation
