The section of ToA on Dungrunglung has this sidebar:

To fool Groak, the characters must paint an image of Nangnang on a surface or craft some other representation of her, then use magic (if they can) to give it a semblance of life. Animate object, major image, minor illusion, and similar spells can help enhance the illusion. Spells such as color spray and prestidigitation can also be used to dazzle an audience long enough to conceal a fatal flub.

[...]

• Painting or crafting a representation of Nangnang requires a successful DC 12 Intelligence check. Using Nolzur’s marvelous pigments grants advantage on the check.

All those spell names (and the Nolzur's marvelous pigments) need to be linked to the corresponding spells/magic item and italicized appropriately.

(There might be others; that's just the ones I noticed.)

This is fixed. Thanks for reporting, and let me know here if you find more on ToA.

 So fast! Thanks.

Ah; you missed color spray and prestidigitation. They're still missing the link.
