Arocknids are level 5, have a base value of 1,500 coins, and have a Web attack. 
To get an Arocknid to appear you must be a level 6 or higher gardener and have 
either four Tafflies or Raisants. It must eat two of either of those to settle 
into your garden. For an Arocknid to romance it must eat two Buzzlegums that 
are already in your garden. Keep them away from Reddhotts to prevent them from 
burning your Arocknids. Feed an Arocknid a Bluebell Flower to turn it blue. 
Feed it a Water Lily Flower to turn it pink. Feed it a Jack 'o Lantern to turn 
it orange. Note: Arocknids can climb trees.
