         <p>
-          There's a new pet breed in town! Check out the brand-new Sand Sculpture Potions and the
-          return of Aquatic and Watery Potions to heat up your Summer avatar look. Get them from
-          <a href='/shops/market'>the Market</a> and use them to hatch any standard pet egg. (Magic
-          Hatching Potions do not work on Quest Pet eggs.) Magic Hatching Potion Pets aren't picky,
-          so they'll happily eat any kind of food that you feed them!
+          For this year's Guild Spotlight series, we're highlighting some favorites from Habitica's
+          staff, moderators, and some high-level contributors!
         </p>
         <p>
-          These potions will be available until Summer Splash ends on July 31. After they're gone,
-          it will be at least a year before these Hatching Potions return, so be sure to get them
-          now!
+          This month we're sharing <a
+          href='https://habitica.wordpress.com/2020/06/25/guild-spotlights-our-favourites-5/'
+          target='_blank'>picks from socialite and translator Nakonana</a>! If you want to curate

+          some new ideas for Guilds to join.
