My New Interests - Thomas The Train and Friends

Lately, I have developed another new like for Thomas The Train and Friends, so I have been pestering for mummy to buy for me when we go out, so till date, I think I have got at least 5 boxes of them, however each time mummy only allowed me to fix up 1 set, if not it will occupy the living hall, and will be difficult for her to clean and pack up. Whenever we start to fix up, its always taking up space and messy.
