Hello,
"summer event quest" : after entering the beach area for first time the Nishy was informed by spirit to look and read some signs on a nearby rock. After doing that, the player should go and interact with the barmen guy, which offers a quick quest (details are shown in [TAB] Book). After completing that the booths unlock. Return every day on beach area for a new dress item unlock (for about 5 days, hair style unlock is last).
*Tip on barmen's quest: throw a carrot at the X mark near the guy's bar, then the second in mid way towards the target, then approach while hiding the target, it should run to both carrots and finish the quest.
"How to shave pets in free mode" : 1 is shaved by TC to unlock more cloths. After the player get's the shaved pet back, must save via sleep (with pet in nest or nearby), then on load the pet should still be shaved.
*I'll try to make the shave option always available on TC after 20 tamings for that type in next update
