OK so I have some research here on Tile Turnip that I've done.
When you hack the game to get unlimited suns via Game Killer, you obviously can get more than eight Tile Turnips. But, if you plant 25 Tile Turnips, you'll get a Tile Turnip seed packet with the cost of negative! Its cost is -100663296, and it doesn't decrease your sun. The reason why this happens is because the game exceeds the max value of 32-bit signed integer (2^31-1 or 2147483647), called integer overflow. The actual sun cost for the 25th tile turnip is 4194304000, but since it exceeds the max value of 32-bit signed integer, it goes to negative.
We can count it by using this:
This also happens to Tree of Wisdom; the max height amount the Tree of Wisdom is 2147483647. When you give another tree food when it reaches that height, it "grows" to its minimum negative height, which is -2147483648.
Below is a brief info of the 1st to 25th Tile Turnips sun cost.
