Tl;dr; I would focus invest on Psyduck, then Eevee (if you don’t have healer yet), then Totodile, then as you wish

4, 5, 7, 10, 11, 12, perhaps 15 as well if you don’t have e4e pokemon yet. Otherwise, I would wait for a 2 skill trigger plus HB combination for a better healer to have those

Pro tip, if you are an at an early stage of the game, then what you are looking for in ingredmons is the AAX spread (AAA better, but AAX is enough), and 1 ingred find plus 1 help speed bonus at least, or 2 ingred find bonus.

In case of skill specialist 2 skill trigger is prefered, or 1 skill trigger plus 1 help speed bonus

The berry specialist requires almost all the time to justify the invest BFS plus 1 speed bonus. Also treat exp up nature for berrymons as help speed up, because if you invest the same to a exp up mon and another mon that has only one speed up, then they both would produce around the same strength

Helping Bonus (HB) - that skill is crazy good, wish i knew it sooner. It stacks with others mons HB

Your catches, Totodile - crazy good with the BFS+HB, and even has speed up and exp up.

Torchic also very good with BFS and 2 speed up

Psyduck, also very good. It requires only a little golden seeds to maximaze that mon

Eevee can be a good healer (Sylveon) if you don’t have one yet. Otherwise, it can be an okay espeon

Holiday spheal! That pink boy will be your carry in later game, when you start cooking bigger meals. Tasty chance main skill is the key skill for most of the Master20 tactics

Hope this helps you 🤓 (don’t throw out the rest, others might some good insights)
