I’ve only seen はいった used as ‘inside’ or ‘enter’

In my eyes this means ‘”there’s a Pokemon logo inside the mug. ( like one of those cups at cafes and there is a logo at the bottom of the drink.)

Or: はいった」(hitta) is a colloquial or casual way of saying:
「貼った」(haritta) – to stick or paste something on

Which is it?
