    No. 12-2142.
    United States Court of Appeals, Eighth Circuit.
    Submitted: March 11, 2013.
    Filed: April 19, 2013.
    Before MURPHY, SMITH, and GRUENDER, Circuit Judges.
   PER CURIAM.

Thirteen homeowners (“Homeowners”) challenge the impending foreclosure of their home mortgages. We affirm the district court’s dismissal for failure to state a claim.

The Homeowners filed suit in Minnesota state court against Wells Fargo Bank, N.A., HSBC Bank USA, N.A., MER-SCORP, Inc., Mortgage Electronic Registration Systems, Inc., and Shapiro & Zielke, LLP (“Shapiro & Zielke”). The Homeowners alleged that each defendant played a role in the invalid assignment of their home mortgages and improper initiation of non-judicial foreclosure proceedings. The defendants removed the case to federal court based on the purported fraudulent joinder of Shapiro & Zielke and then filed motions to dismiss all claims. The district court denied the Homeowners’ motion to remand and granted the motions to dismiss.

“We review de novo the district court’s grant of a motion to dismiss under Rule 12(b)(6), construing all reasonable inferences in favor of the nonmoving party.” Retro Television Network, Inc. v. Luken Comm’ns, LLC, 696 F.3d 766, 768 (8th Cir.2012). We affirm the district court’s decision to deny remand based on fraudulent joinder and to dismiss the claims against Shapiro & Zielke. See Murphy v. Aurora Loan Servs., LLC, 699 F.3d 1027, 1031-32 (8th Cir.2012).

As to their claims against the remaining defendants, on appeal the Homeowners have abandoned all but a claim to quiet title under Minnesota Statute section 559.01. See Murphy, 699 F.3d at 1032 n. 3; Marksmeier v. Davie, 622 F.3d 896, 902 n. 4 (8th Cir.2010). The vast majority of the bases for this claim are tied to the “show-me-the-note” theory, “which argues [that] the holder of legal title to a mortgage cannot foreclose if he is unable to produce the underlying promissory note.” Murphy, 699 F.3d at 1030. The Minnesota Supreme Court, as we have previously recognized, has denied the viability of this attempt to challenge a non-judicial foreclosure. See id. at 1030-31; see also id. at 1033 (affirming dismissal of portions of a quiet-title claim because the alleged defects in the defendants’ ability to foreclose were “regurgitations of the ‘show-me-the-note’ theory”). The quiet-title claim in this case is a carbon copy of the quiet-title count in the Murphy plaintiffs’ complaint. As in Murphy, “two of the quiet-title theories do not rely on the failure of the foreclosing party to produce the note,” and accordingly they avoid the taint of the soundly rejected “show-me-the-note” theory. Id. at 1033. Nonetheless, the district court properly dismissed these claims for “alleg[ing] mortgage invalidity on the basis of various assertions that are wholly unsupported by facts.” In Karnatcheva v. JPMorgan Chase Bank, N.A., this court held that identically worded claims were deficient under federal pleading standards because they were nothing more “than labels and conclusions, based on speculation.” 704 F.3d 545, 548 (8th Cir.2013). Accordingly, we affirm the district court’s dismissal for failure to state a claim.
