Maybe there could be a Item that if you put it on a pokemon it
doubles its interactions? Just a thought so people don't have to
wait for it to be double day c:
'Double interactions' meaning doubling the EHP/EXP gain every
interaction the Egg/Pokemon gets? If so, there is already an item
that does that. You can buy it at the Item Shop for 23/90/270
nuggets.
Yellow / Red / Blue Flutes are the Items that do this. Their
description states the following: Doubles EXP/EHP increment for [24h/7d/30d]. Only affects the
Pokémon/Eggs placed in your Party.
