Odin removed the weeds using his tail and knocked on the rock which they thought would be an entrance. The rock got smashed and created a hole, and with that, the entrance is created making them happy. Finally, they will be able to see the creature which is playing with them for a long time. Both dragons planned to go inside on their own but Gavon suggested that he will also come along with them because he is the reason the dragon's presence is known to them. Ivy also wants to go inside and look at the Dragon which is awakened by Gavon's blood awakening.
Both dragons want to stop them but after hearing their reasoning they didn't stop them and instead protected them from both sides. Before they enter, Odin wants to check for any dangers and spit the fire to see inside the dark cave. His fire lit the whole cave when it is moving inside making the insects or other things crawl out of it.
