"what's the first part", you ask? we recommend replacing the cartridge with a 4-person household after 6 months. you never know that he might just be your perfect travel buddy to fill your trips with excitement and fun. lighting is still an issue but at least things are more accessible now. we drove off-track for about five minutes, when we came to a clearing with 5 lions – one cub and four adults. if you have any questions about the use of the designs, please contact us on our support e-mail.
