Need Help Recreating Bob-omb X-ing

I need help. I am currently trying to recreate the Bob-omb X-ing minigame from Mario Party 4 in Unity 3D. The main issue I'm running into right now is creating the spawners for the Bob-ombs. I also still need to add animations, make the bombs explode, and make them deal damage to Mario. Is there anyone who would be willing to help me, or is there a group/community that focuses on this type of project?
