I already submitted my design in the link but wanted to share it because its kinda fun, certainly was to write it. It was based on a particular video some months ago I found fun to watch ( https://www.youtube.com/watch?v=7blp_fW64QE ). Please note that the numbers were mostly made up and I have no idea what numbers are good and balanced.

Druid - Circle of the Bees
Themes: Bee Companion, Honey Magic
Note: To offset the gain of two Features, a Circle of the Bees Druid cannot shapechange and loses any related Feature.
Level 2 Feature:
Bee Companion 1: Youre followed by a tiny sized Bee Companion. You can name your Bee Companion but it is always a female bee, reason is that only female bees can be queens, see Level 14 Feature, so keep that in mind. In addition to flying, it has a bite attack for a tiny amount of damage and can use its sting 1x per encounter for a small amount of damage.
Honey Magic 1: You gain a special version of the Magic Stone Cantrip called Honey Stone. This is a Conjuration spell instead of a Transmutation spell. Instead of transmuting up to 3 magic pebbles, you create only 1 pebble made of honey. It does damage as normal vs enemies but also causes a -1 penalty to his next attack, gives the next attack against him that bonus or has a 10% chance of causing a spell failure for that enemy if it is a spellcaster, whatever comes first but within 1 round. You can also use your honeyed pebble vs your Bee Companion which causes it to miss the next round but be healed for half the amount of damage Magic Stone would cause. This Feature replaces the Wild Shape gained at Level 2.
Level 6 Feature:
Bee Companion 2: Youre followed by a small sized Bee Companion. In addition to flying, it has a bite attack for a small amount of damage and can use its sting 1x per encounter for an average amount of damage.
Honey Magic 2: You gain a special version of the Erupting Earth 3rd level spell called Erupting Honey. This is a Conjuration spell instead of a Transmutation spell. Instead of creating a fountain of churned stone in an area, you create a fountain made of honey in an area. It does damage and effects as normal vs enemies but also causes a -1 penalty to each enemies next attack, gives the next attack against each enemy that bonus or has a 10% chance of causing a spell failure for that enemy if it is a spellcaster, whatever comes first but only for 1 round. In addition, your Bee Companion is healed for 1d6 HP every round it ends within the area of Erupting Honey. This Feature replaces the Wild Shape Improvement gained at Level 4.
Level 10 Feature:
Bee Companion 3: Youre followed by a medium sized Bee Companion. In addition to flying, it has a bite attack for an average amount of damage and can use its sting 1x per encounter for a large amount of damage. Your Bee Companion also gains access to 1 damaging Cantrip of your choice of any spellbook origin and can use it every 3rd round.
Honey Magic 3: You gain a special version of the Cone of Cold 5th level spell called Cone of Honey. This is a Conjuration spell instead of an Evocation spell. Instead of creating a blast of cold air, you create a blast made of honey. It does damage and effects as normal vs enemies but also causes a -1 penalty to each enemies next attack, gives the next attack against each enemy that bonus or has a 10% chance of causing a spell failure for that enemy if it is a spellcaster, whatever comes first but only for 1 round. Enemies that die from this spell become a honeyed statue that you or your Bee Companion can 'use', Bonus Action, to regain 4d8 HP if adjecent to that enemy. The enemy remains in this condition for 3 rounds and each time it is used, the amount of healing is halved so youre able to use it 3 times at most. In addition, your Bee Companion is healed for 2d8 HP if it is within the area of Cone of Honey when cast. This Feature replaces the Wild Shape Improvement gained at Level 8.
Level 14 Feature:
Honey Queen: Youre followed by a medium sized, special skinned (normal Bee Companion is black-yellow, Queen Bee Companion is also black-yellow but has one red ring, it is also slightly larger but still medium-sized), Bee Queen Companion. In addition to flying, it has a bite attack for an average amount of damage and can use its sting 2x per encounter for a large amount of damage. Your Bee Companion also gains access to another 1 damaging Cantrip of your choice of any spellbook origin and can use either of its Cantrips every 2nd round.
Royal Gelly: You gain the unique Bee Hive 7th level spell. This is a Conjuration spell. It creates at the point of target, a large golden shimmering bee hive of honeyed goodness. Each round, any enemy within medium range of the bee hive is harassed by annoyed bees and gets a -1 penalty to his attack, gives attacks against him a +1 bonus and has a 20% chance of causing a spell failure for that enemy if it is a spellcaster for as long as the bee hive persists. Enemies that die while withing the spell area become a honeyed statue 3 rounds later as bees from the hive start gathering honey around them that you or your Bee Queen Companion can 'use', Bonus Action, to regain 4d8 HP if adjecent to that enemy. The enemy remains in this condition for 3 rounds and each time it is used, the amount of healing is halved so youre able to use it 3 times at most. In addition, each round your Bee Queen Companion is serviced Royal Gelly by the Bees and healed for 2d8 HP if it is within the area of Bee Hive. The Bees also service you and your party members with honey, healing 1d6 HP for everyone that is within the area of Bee Hive. The Bee Hive persist until end of combat or it is destroyed. It has half the HP of your Bee Queen Companion and any enemy that attacks it is instantly attacked by all Bees, disabling any healing serviced and doing 4d8 damage to that enemy without fail. This Feature replaces the Beast Spells gained at Level 18.
Level 20 Feature:
Archdruid - Circle of the Bees: You can ignore the verbal and somatic components of Druid spells like other Archdruids. In addition, your Bee Queen Companion now has access to the Honey Stone Cantrip and can cast Erupting Honey 2x and Cone of Honey 1x per Long Rest, healing you as if you were a Bee Companion. Your Honey Magic spells affect you as if you were a Bee Companion too.
Edit: Tweaked some aspects.
