Tinykin

Before setting out you should make sure you have at least 25 red Tinykin, though there are a few on your way up to the top of the cupboards.

The ice cube in question is in the freezer in Ambrose, (the top part of the fridge-freezer to the right of the door you enter Ambrose through).

In order to access the freezer you need to get on to the top of it. Access is from the top of the cupboard to the left of the fridge-freezer, (where the Mantis dining table is). The way up to the cupboard tops is via the green shelves to the left of the hob top, (gas burners), up the cutlery stairs, across the hanging lights and donuts above the hob top and up the leaves on the side of the cupboard.

Once on top of the freezer you will see a large chunk of ice holding the door closed, you will need 4 red Tinykin to blow this up, which will open the freezer and give you a short cut-scene highlighting the ice cube in question.

Drop down, (making use of your glide bubble), collect the 5 red Tinkyin and then blow up the massive ice cube, collecting the pollen inside and this achievement).
