Haggisland lies underneath Scotland. We have all our own towns, villages, cities, rivers and tunnels (like your roads) usually underneath a similar place “up-top”.
The tunnels mean we can travel really, really fast. There are lots and lots of tunnels that have already been dug. If there isn't a tunnel to where we want to go we can just dig a tunnel there and then it is there for anyone who wants to use it.
The tunnels let us get everywhere in the world faster than you because if there is a hill or mountain we either dig through or under it. We also just dig under water, so all our tunnels are straight lines, we also don't get wet if its raining outside and we need to go somewhere.
We have friends and family all over the world and sometimes we go on holiday or a visit and if they need us to we go and help them.
