I come to you with an inquiry concerning an animal in the garden. It has long claws and teeth, and immediately burrows underground when I approach it. Its tail also appears to be on fire. What on earth is it?
"To my beloved pupil,
From your description, it could only either be a fire Moler or Diggron. You would do well to befriend it, as it will be a great companion should you ever become a master. I suggest bringing an apple with you next time to 'break the ice', so to speak.
"To my esteemed mentor,
Your wisdom never ceases to amaze me. Thanks to your advice, I became friends with the Diggron, who has now evolved into a Quarrik. I am now thinking of officially becoming a master and entering the Astromon League. Next we meet, I would love to introduce you to my new friend.
At times, a water Moler's playful pranks may feel malicious, but they are actually a sign of affection. While they may take getting used to at first, after a while checking for leaf-covered holes in the ground filled with muddy water will become second nature.
When bringing a Diggron aboard an airship, it is important to lay some ground rules, such as "No digging."
"When irrigating a new tract of land, it is essential to have a water Quarrik available to dig the canals. If no Quarriks are available, a Diggron maybe be used as a substitute, but the Quarrik's more agreeable personality makes it the ideal choice."

Molers loves to use their highly developed claws to dig caves to hide in or traps for predators, the latter of which also serve as children's favorite excuse when caught covered in dirt: "I fell into a Moler trap!"
A Moler's evolution into a Diggron brings with it faster and more agile movement underground, allowing it to easily launch surprise attacks from below. However, due to its peaceable nature, a Diggron will almost never attack unless provoked.
Following in the same vein as its claws this Astromon's tail has also evolved to aid in the digging process. Now, in addition to dispatching of foes with its powerful claws, a newly-evolved Quarrik can also wreak havoc by digging under and bringing down small buildings.
