Moo RPG 2

You should orient the number pad to be adding machine style instead of phone style. You don't do math on a phone's pad, you always use adding machine style number pads(such as what's found on calculators and computers). If the goal is for the game to be educational, then you should be familiarizing children with the orientation common to calculators and computers, not phones. Additionally enable use of computer keys so kids can actually use the number pad on the keyboard instead of the mouse.

still don't know how to trigger a gold udder

An educational game, indeed. If you ever find yourself involved in a social group or a business venture that functions in a similar way to this game, you have most likely actually fallen into a cult or a multiple-level marketing scam, and should disconnect from the group, and possibly contact the authorities or seek professional help.

highlighting items which i can craft would be nice :)

Several "bad" design decisions for educational game. Defense school is first(only so far for me) part of game that uses keyboard and cow. Energy replenishes slowly, is labeled "turns"(confusing, remember, educational game) and there is no clear indication how it's used up, no way to actively replenish it.
