Ankoopa #7
Path Blocked: Alternate path to Teehee Valley / Piranha Bean's area.
North East of Beanbean Castle Town at the beach of Beanbean Fields on the bridge above (knocking over this Ankoopa is optional but works as a shortcut and more convenient route).

In the house closest to Starbeans Café in Beanbean Castle Town. This Ankoopa isn't blocking a path but rather just lives in the house and as a result, cannot be knocked over.
Etymology
Ankoopa's name is a combination of "anchor" and "Koopa". An anchor is a heavy object attached to a vessel, relating to Ankoopa as being heavy to move.
