The recovery method of seed bags in the Fat Goose Gym is that two bags with the highest grade are combined, and two empty bags with grade 4 (8 empty bags in one grid) need to be combined with 16 empty bags.
That is to say, two top-level seed bags are combined with two four levels, the flowerpot produces seed bags, the seed bags produce seeds, the seeds are synthesized into trees, and the trees automatically produce snail shells, and the used seed bags are synthesized into cloth-bag dolls.
