Saobtender evolution rate is unreasonably low

[Leny]

I've raised every monster in the garden multiple times and the only one I ever have any issue with is the sabotender. it takes stacks of sunflower seeds even during the campaign every time. It's absolutely ridiculous. No other monster takes more than 2 or 3 items and at most maybe 6, but it's not uncommon to use 30+ sunflower seeds.
