I just got him 3 days ago, First pac man, 7th frog. He didnt burrow he just walked around exploring On day 1 and 2, Day 3 he dissapeared! I chek and he burrowed all the way down! about 2 inches, Than when I found him he immedeatly starting jumping around trying to escape, I tryed offering a cricket and earthorm, all he tryed to do was get out. He is about a half dollar size in a 12qt container, ventilated, 85 Humidity, 79F temp.
