He is heartsick at the loss of the wyrmling and spends much of his time nowadays in nightmare-ridden sleep in his bedroll. With the loss of his charge, Meepo's status is in the gutter. He doesn't react to anything short of loud noise or direct prodding.>If he is disturbed, Meepo is frightened but willing to talk. He is weepy. His numerous obvious scars are souvenirs of his job as Keeper of Dragons. If he is asked about the cage or queried in any way that mentions a dragon, he says, "The clan's dragon... we lost it. The wretched goblins stole Calcryx, our dragon!">To all other questions, Meepo responds by saying, "Meepo don't know, but Yusdrayl does. Meepo take you to meet Yusdrayl, our leader, if you make nice. You get safe passage, if you promise to make nice. Maybe if you promise to rescue dragon, Yusdrayl make nice to you, answer questions.">Meepo perks up as he senses the possibility of getting the dragon back. True to his word, he guides the characters to area 21. Along the way, he shouts out "Ticklecorn!" (in Draconic) from time to time, explaining that it's a password that tells other kobolds the characters are friendly. If the characters leave Meepo behind, or if they are antagonistic toward him, the characters don't learn the password, and all other kobolds are hostile toward the party.https://dungeonsdragons.fandom.com/wiki/MeepoThey just killed and ate Meepo, their only significant chance at a friend in the Sunless Citadel.
Also, the DM keeps on forgetting that ranged attacks with a hostile enemy within 5 feet take disadvantage.
