My 1st Post on this forum Ok..I have some ideas !!
1: Perhaps a pet dog/cat/T-rex that you can feed and stuff and they can drink out of the pool
2: Fridge where you can eat, maybe add a thing where she eats once a day or something.
3: A Lake in the yard and a boat!!! or a Road coarse for a bike/car
4: Deeper pool with more tunnels
5: Have day time and night time
6: More outdoor places to go, like a outside training area
7: Winston shouldnt be depressed anymore Suprised he hasnt caught fire yet lol. Make him walk around and do normal things like sit down and stuff.
