"A cleverly engineered promotional polybag with genuinely rare parts and a charming transformation gimmick, the Mini Piggy Bank earns its Recommended BrickScore of 74.9 as a free bonus that over-delivers on design despite the sticker-eyes shortcut."
The Mini Piggy Bank (40251) is a 2017 promotional polybag that reviewers generally find charming and cleverly designed without being exceptional. Brickset praises the new curved-body design as a vast improvement over the previous 40155, highlighting the three-animal transformation mechanic and the inclusion of genuinely rare parts. JANG offers a more measured take, noting that the alternate builds require only minimal swapping rather than full rebuilds, and that sticker eyes rather than printed ones are a disappointment. Owner data is very limited (only 3 LEGO.com ratings averaging 4.0), so no broad buyer consensus can be drawn.

"This new design is very distinctive, with a curved body and a stubby shape which looks brilliant in my opinion."
