The app ruined my spaceHey page

It got rid of all my little side things I had a windows media player that would link to a destroy boys song on YT, I had slenderman in the bottom left corner, I had a silly kitty that would be in the corner and wave, and I literally had furbys but I don’t see them anymore, and I had it so it’d rain rainbow stars and stuff like what happened? If anyone knows how to fix this PLEASE comment below. Is it just the app? Is it just how I designed my layout? Please help :(
