We have Double-Decker bus
Double-Decker Taco

Double-Decker Burger
Now we even have Double Decker Millipede!!
We were surprised to see the double millipedes appearing at the back of our house. It's the first time we saw something like this and we wondered what they were actually doing...Egg's guess was making babies??!! Hmmm....
Anyway, since there's Double Decker millipede, then we're gonna have our own version of Double Decker too!
