Those sticks are drumsticks, of course, for the featured Pokémon is Grookey, the Grass-type first partner from the Galar region, also making it likely that the rest of its friends will also make themselves present later this year. Being a first partner, the move of Frenzy Plant as its special move should have already been a given, though it also has the opportunity to learn its signature move of Drum Beating by TM. This is complemented by the bonus of triple catch Stardust, which is always wonderful to have and earn.
For the rest of the bonuses, they're as regular as regular can be. They are double Candy and Candy XL chance, three-hour Incense and one-hour Lure Modules (with its extra appearances), trade discounts and extra Special Trades, photo bombs, and special backgrounds in the wild (since the Classic Piplup edition) and from Research. Speaking of which, Field Research is of the usual sort, and there is also the paid Special Research with the title of "Grooving with Grookey". The "groove" also applies to the rest of the bonuses.
Being that it was my "special day" the other day, I decided to do something special and visit a faraway community to interact with them... though their place remains familiar for other purposes, which also became a part of my day today. I caught just enough Shiny Grookey to have a stock, and I caught a few special ones with the special background. The main purpose of evolution today was just to obtain a few that needed the Frenzy Plant move, while others (as the G-Max Rillaboom I already had) could use the Drum Beating move.
With regard to variety, as far as that goes, first partners that not only have their "super" moves but also signature moves of their own presents a good kind of variety, as shown in editions of Community Day in the past few years and even today. This year will surely have that and more - which are to be determined soon - and the sticks that Grookey and its species family wield are the lead-off for that variety and all the ways it may be realized.
