2022-10-07 : +1/+1 counters aren’t “attached” to the creatures they’re on like an Aura or Equipment is, so a +1/+1 counter/Food token that becomes a creature stays on the creature its on. It still gives that creature a +1/+1bonus. It doesn’t give itself a +1/+1 bonus. Note that +1/+1 counters/Food tokens don’t have a mana cost, so their mana value is 0. Many ways of turning them into creatures will turn them into 0/0 creatures, so unless something else is raising their toughness, they’ll immediately spoil . . . er, die.

2022-10-07 : The +1/+1 counters that are also Food tokens are still +1/+1 counters. They should stay on whatever permanent they were on, even though they become permanents themselves. That acorn symbol at the bottom of the card isn’t messing around here.

2022-10-07 : The +1/+1 counters/Food tokens are artifacts, so anything that counts artifacts will count them. They can be tapped, untapped, sacrificed, and so on. They can even attack and block if you find a way to make them creatures.

2022-10-07 : The activated ability doesn’t target any creature. You choose which creatures get counters after you roll the dice. If you roll two odd numbers, you may put both +1/+1 counters on the same creature.
