mango seed?

Something had been pushing up through the soil in the pot I planted a Mango seed in. At first I was excited, thinking I'd finally see a seedling. But it's been like this for over two weeks, static. I finally upended the pot to find out what was going on. The soil was all saturated, no roots at all, and the seed fell apart in two halves. I guess it was rotting. Try again next time we eat a mango, maybe a different method. And not too much water!
