I tried this for about a month and didn't get any of the trio. In fact I didn't get any of the 6 special breeds this month except for alpine elephant. Maybe my breeding den is spoilt or my forest is unbreedable, as always. The only small consolation is that I could get alpine ele to complete the SB. Anyone failing as badly as I did, or is it just me? 1 out of 6 is miserable.
