Lilo and Stitch Easter Egg - 7:15, Many Mickeys, and Other A 113s in the Movie

There are three times 7 15 show up in the movie.
First when Nani comes into Lilo's room to give her pizza it shows a licence plate in the background which says 7 15.
Second when Lilo wakes up Nani to show her that Stitch can play music with his mouth it shows Nani's digital alarm clock which also says 7:15.
Third after Stitch runs away and it shows Nani waiting for the social worker it show a clock. The hour hand is pointed at 7 and the minute hand is between 2 and 3.
Go to the end where it shows the Christmas scene (When Jumbu dresses up as Santa). At the top there is a plant hanging across the screen. It has three berries that look tike Mickeys. Also one of the presents has wrapping paper with berries shaped like mickeys with leaves.
Also at the end when there's a picture of them washing the new beetle. The licence plate says A 113. The scene where Stitch makes a model of San Francisco it shows a billboard that has a licence plate that says A 113. After the aliens wreck the house it shows Nani. A fire truck goes by with the licence plate says, gues what, A 113.
When Stitch takes the old buggy and throws it at Jumbu and if you pause it at the right time (exactaly 01|24|1:01:38) you'll see that the licence plate says LS 2153.

If anyone knows anything about the 7 15s or the LS 2153 please tell me.
