Ushi No Tane - Harvest Moon

I can't tame death wall. I'm level 221 and I throw ice cream for hours after he comes off the wall, but he won't love me. What's going on?

A. Might have to be a much higher level then Death Wall to tame him.
Or B. Make more space in your barns so then the heart will stay and let you name him.

1Craft a happy ring
2Grow some clovers and or big clovers
3Put how many you like on your happy ring
4Try fishing for the sand flounder/rockbane fish> 4a get and keep all rare cans

5. Try brushing Death Wall before you tame, and make sure it's off the wall

Extra
Dont hit with any weapoms :....(
Craft all the Ice Cream you want
Craft A Rosary
Death Wall tameable

You can also put rare cans or clovers on your equipment, mine are in my bag, they helped me get rare cans

-o.0 also hero proof sounds good as I never hit the bosses I tame :-/
Happy Harvest
