Q.: How to improve the looks of the backyard?
A.: All you need is an active NFC spot. For example on your phone, or tablet. It does not have to be a device compatible with the 4U / 4U+, just an active NFC spot.
Without selecting any icons, just touch the back of your Tamagotchi 4U / 4U+ with the active NFC spot. After a short while there should appear a short, random animation on your Tamagotchi.
That counts as one touch. The more NFC touches your Tamagotchi gets, the nicer your yard will look.
0-3 touches
4-19 touches
20-99 touches
100-999 touches
SUPER MEGA AWESOME BACKYARD!
1000 touches!
