Mikey will be opening Hull city's new Poundland store in Ferensway.
He will meet visitors on Saturday and sign autographs. From 10am he will be giving out £1 vouchers, which shoppers can exchange for anything from multi-bags of Walkers Crisps to greeting cards.
They can also take part in Poundland Lucky Numbers when £100 of store vouchers will be up for grabs, as well as enjoying music from the in-store DJ.
