>>53525828There were several tomigachis released over the years, pretty sure an eevee one was released recently, so you could mean any one of those, but the minigames part makes me think it may have been the pokemon mini. If So, not lost, Pokemon Channel contains most the games (and I believe a couple that never got a physical release on the original hardware, but that may have been something I misread somewhere years ago) and you can still buy them on ebay.
