Tamatown tama-go unlocks? also is there a evolution chart?

[Taft]

is there a way to unlock new stuff like food for the tamatown tamago? it gets kinda boring since im so limited. Also does anyone know if there is a growth chart for this tamagotchi generation? ive restarted a couple times just because i played with it a little but then left it and i feel like everytime i play it i get the same type of tamgotchi (he looks like a big ball of slime with a face tahts kinda like a jack o lantern)
