Did you ever figure this out? I am just a baker for the fun of it and I have been trying to figure it out. I thought that once the elephant was made (fondant and tylose) that it would be hard and I could just wrap the wire around the trunk. It would be a styrofoam ball covered in fondant or candy melts. To get the elephant from toppling over, the elephant would probably be secured deep into the cake?
Aoh my gosh -- this came up before and I advised to securely anchor the elephant down into the board that the cake sits on otherwise the imbalance of weight will topple it over -- the head of the elephant and the balloon make a majority there that cannot be dismissed/overlooked -- so I would insert a couple bamboo skewers into the legs of the elephant that will fit/stick into the board for stablity
