Spelunk is the most removed mole from society ever seen. He hoards a massive amount of treasure and anyone that gets near it will never be able to see the surface world again. After Sonic saves him from being crushed by a falling boulder, which was from Robotnik digging into the cavern, Spelunk has a change of heart and allows Sonic and Tails to leave. He even assists them in getting his treasures back from Robotnik. Realizing the true value of friendship, Spelunk uses some of his treasure to buy Chili Dogs for Sonic and Tails.
Spelunk later returned in the episode "Hero of the Year" where he attended the banquet in Sonic's honor.
Initially, Spelunk was cranky and not were trusting of anyone. He was willing to keep anyone and do anything in order to keep his treasure safe and regarded the treasure buried in his cave as his only friends. However, he eventually realized the error of his ways, becoming much more friendly and charitable.
