07700 43999- lucky creature
07700 43090- lucky cat
07500 43199- party favors
07500 43290- DVD
07500 43391- aqarium
07500 43492- disco ball
07500 43593- stereo
There are a lot more codes, you can figure them out by using the patterns.
you can just do either 07700, 07500, 07400, 07600, 07800, 07900, 07100, 07200, 07300, 07000
or more for the first 5 numbers in the code then, do 4,3 and then i would start from one first and then do 9 and then put in a number and if it dosnt work when you press the b button keep putting in numbers until the code works. Do this starting from one first and then all the way through 0 for the 2 numbers that are on each side of the number 9 in the coddes. All codes have one of the listed first 5 numbers in it or more and then has 4,3 another number, 9, and another number. ( look at the codes i gave above for examples) Hope i could help. Pleas send comments or any questions or concerns. Thank you! : )
