Source: npc/quests/quests_amatsu.txt

1. In Amatsu event flow (Momotaro Field Trip), reward comes from a random prize table.
2. One branch is case 1: getitem 622,1; //rainbow carrot.
3. Complete the event run and reach the reward-distribution segment.
4. Since it is random-table based, Rainbow Carrot is not guaranteed each run.
